Assessing the fatigue performance of welded tubular joints is crucial to the safety and durability of their host structures. Fast-computing beam-element models are insufficient to accurately capture local stress concentrations at the intersection region, leading to inaccurate lifetime predictions. In this work, a high-fidelity numerical modeling tool, HFJOINT, is developed for stress concentration analysis of welded tubular joints, following a user-friendly process. The workflow begins with the creation of an elementary T/Y-joint using quadratic hexahedron elements, where the weld geometry is generated in accordance with the American Welding Society (AWS) standard. The chord and brace are divided into several regions allowing for an entirely structured mesh. The geometric transformations of multiple elementary joints enable creating more complex joints. After evaluating the stiffness matrix, the beam-element forces are converted to external tractions, and are transformed into solid-element nodal forces via Gaussian integral. The boundary conditions are defined from the geometric constraints formulated by the Lagrange’s equation of the second kind. Based on the nodal displacements, the postprocessing module evaluates the local stress at any point. Using linear extrapolation, the hot-spot structural stress and the stress concentration factors (SCFs) along the weld circumference are computed. The workflow has a computational complexity of

O (N^{1.89})

. The mesh convergence shows that the relative changes are below 2% when refining the weld circumference from 64 to 96 segments. The tool is verified against the SCFs of benchmark T-, K- and X- joint models, showing its potential for fatigue analysis of welded tubular joints in broad applications.

评估焊接管接头的疲劳性能对其主体结构的安全性和耐久性至关重要。快速计算的梁单元模型不足以准确捕获交叉区域的局部应力集中，导致不准确的寿命预测。在这项工作中，开发了一个高保真的数值建模工具HFJOINT，用于焊接管状接头的应力集中分析，遵循用户友好的过程。工作流程从使用二次六面体元素创建基本T/ y型接头开始，其中根据美国焊接协会（AWS）标准生成焊缝几何形状。弦和支撑被分成几个区域，允许一个完全结构化的网格。多个初等关节的几何变换可以创建更复杂的关节。计算刚度矩阵后，将梁单元力转换为外部牵引力，并通过高斯积分转换为实体单元节点力。边界条件由第二类拉格朗日方程所表示的几何约束来定义。根据节点位移，后处理模块计算任意点的局部应力。采用线性外推法，计算了焊缝周边的热点结构应力和应力集中系数。工作流的计算复杂度为0 （N1.89）。网格收敛表明，当焊缝周长从64段细化到96段时，相对变化小于2%。该工具通过T型、K型和X型接头模型的scf验证，显示了其在焊接管接头疲劳分析中的广泛应用潜力。

Metaheuristic algorithms are widely recognized as valuable optimization tools in numerous real-world applications due to their strong global search abilities, adaptability, and robustness. The grey wolf optimizer (GWO) is a widely adopted classical algorithm in this field, with IGWO representing a prominent improved version. To overcome the shortcomings of IGWO in global exploration, the imbalance between exploitation and exploration, and the static nature of neighbor selection in the DLH strategy, this paper introduces a novel metaheuristic algorithm called MYIGWO. The algorithm integrates a dual mutation strategy, adaptively selecting mutated individuals via differential random perturbations. By ranking individuals according to fitness, Cauchy mutation is applied to some lower performing individuals to strengthen global exploration, while the remaining selected individuals are subjected to polynomial mutation to enhance convergence speed and the ability to avoid local optima. Additionally, a directional correction is introduced to the mutated individuals to stabilize the mutation outcomes. Lastly, the DLH strategy’s neighbor radius is dynamically adjusted using chaotic mapping, enabling flexible neighbor selection. The optimization performance of MYIGWO was systematically evaluated using multiple performance metrics, and MYIGWO was compared with eighteen advanced meta-heuristic algorithms on multiple benchmark test sets. Moreover, MYIGWO was applied to four classical engineering optimization problems and robot path planning task. The results show that MYIGWO exhibits significant performance advantages in all experiments. In particular, it showed significant improvements in the global optimal solution search capability over the original algorithm. We make the code publicly available at: https://github.com/zhy1109/MYIGWO.

元启发式算法由于其强大的全局搜索能力、适应性和鲁棒性，在许多实际应用中被广泛认为是有价值的优化工具。灰狼优化器（GWO）是该领域中被广泛采用的经典算法，其中IGWO是一个突出的改进版本。为了克服IGWO算法在全局探索、开发与探索之间的不平衡以及DLH策略中邻居选择的静态性等缺点，本文提出了一种新的元启发式算法MYIGWO。该算法采用双突变策略，通过微分随机扰动自适应选择突变个体。根据适应度对个体进行排序，对部分表现较差的个体进行柯西突变，加强全局搜索，对剩余选择的个体进行多项式突变，提高收敛速度和避免局部最优的能力。此外，对突变个体进行定向校正以稳定突变结果。最后，利用混沌映射动态调整DLH策略的邻居半径，实现灵活的邻居选择。使用多个性能指标对MYIGWO的优化性能进行了系统评价，并在多个基准测试集上与18种先进的元启发式算法进行了比较。并将该算法应用于四个经典工程优化问题和机器人路径规划任务。结果表明，MYIGWO在所有实验中都表现出明显的性能优势。特别是，该算法在全局最优解搜索能力上比原算法有了显著提高。我们将代码公开发布在：https://github.com/zhy1109/MYIGWO。

This study investigates the enhancement of seismic performance in tall buildings by utilising passive friction-tuned mass dampers (PFTMDs), with a specific emphasis on the impact of soil-structure interaction (SSI). The novelty of this work lies in integrating multi-objective optimization of PFTMDs with consideration of SSI effects, providing a comprehensive comparison with active damping strategies under various soil conditions. A multi-objective marine predator algorithm (MOMPA) is employed to optimize the damper parameters. The analysis incorporates four earthquake ground motion records and three soil types: soft, medium, and dense. The optimized performance of the PFTMD is compared to that of an active friction-tuned mass damper (AFTMD), which is controlled by a proportional-integral-derivative with filter (PIDF) controller, also optimized via MOMPA. Both control strategies are benchmarked against an uncontrolled structure. The results indicate that both systems significantly enhance the seismic performance of the structure by reducing displacement, acceleration, and inter-storey drift. However, the AFTMD consistently outperforms the PFTMD across all soil conditions. To account for the unpredictability of seismic events, the study further assesses damper performance using averaged parameters derived from multiple earthquake-soil combinations. While the PFTMD performs effectively when tuned for specific conditions, its performance declines under averaged settings and can even amplify structural responses. Conversely, the AFTMD shows robust and consistent performance, establishing it as a more reliable solution for seismic mitigation in tall buildings.

本研究探讨了利用被动摩擦调谐质量阻尼器（pftmd）增强高层建筑的抗震性能，特别强调了土-结构相互作用（SSI）的影响。本工作的新颖之处在于将pftmd的多目标优化与SSI效应相结合，在不同土壤条件下与主动阻尼策略进行了全面比较。采用多目标海洋掠食者算法（MOMPA）对阻尼器参数进行优化。该分析结合了四次地震地面运动记录和三种土壤类型：软土、中土和致密土。PFTMD的优化性能与主动摩擦调谐质量阻尼器（AFTMD）进行了比较，后者由带滤波器的比例-积分-导数（PIDF）控制器控制，也通过MOMPA进行了优化。这两种控制策略都是针对非受控结构进行基准测试的。结果表明，两种体系通过减小位移、加速度和层间漂移，显著提高了结构的抗震性能。然而，AFTMD在所有土壤条件下的表现都优于PFTMD。为了考虑地震事件的不可预测性，该研究进一步使用从多个地震-土壤组合中得出的平均参数来评估阻尼器的性能。虽然PFTMD在针对特定条件进行调整时表现有效，但其性能在平均设置下会下降，甚至会放大结构响应。相反，AFTMD表现出稳健和一致的性能，使其成为高层建筑中更可靠的抗震解决方案。

The gearbox vibration of a planetary gear set is caused by multiple meshing excitations associated with different gear pairs. Decoupling the vibration signal helps analyze the influence of each gear pair on the vibration response of the planetary gear set. To achieve this, a dynamic model and a vibration signal model are proposed in this study. In the dynamic model, the flexibility of the ring gear is considered, and the vibration response of each gear pair is calculated separately. The vibration signal model incorporates the characteristics of the vibration signal and its transfer paths. A parameter identification technique based on the particle swarm optimization (PSO) algorithm is applied to estimate the unknown parameters. The vibration response corresponding to each gear pair is constructed according to identified parameters and vibration signal model. The effectiveness of the proposed methods is validated through experiments conducted on a planetary gear test rig. Results demonstrate the ability of the proposed methods to separate gearbox vibration components. Compared with the dynamic model, the vibration signal model combined with parameter identification is easier to implement for this task.

A new computer-aided framework for assessing the creep deflection of reinforced concrete (RC) beams retrofitted by pre-stressed CFRPs, utilizing a combined experimental and numerical approach, is presented. The framework leverages automation in structural analysis through the development of a custom ABAQUS subroutine, which implements the Age-Adjusted Effective Modulus (AAEM) method to evaluate creep behavior in both the composite and concrete materials. Designed for non-linear analysis, the proposed model offers a tool for integration with other computational systems, enhancing its applicability across the construction life cycle. The methodology is validated through a combined experimental and numerical approach. A series of tests was conducted on RC T-beams strengthened with pre-stressed CFRPs subjected to sustained loading for one year. The accuracy of the framework is further corroborated by comparing its predictions with experimental data from both the current study and existing literature. Results demonstrate that the proposed framework provides a robust, automated solution for creep analysis, offering a simplified yet precise method for practical engineering applications in the design, maintenance, and management of constructed facilities.

Triply periodic minimal surface (TPMS) lattice structures, especially Gyroid structures, evidence great potential in the field of lightweight multifunctional structures due to their excellent specific strength, specific stiffness, and tunable energy absorption properties. However, the complex geometrical properties of the structure lead to huge simulation complexity for high-precision dynamics simulation, and the existing equivalent parameter acquisition methods are difficult to accurately characterize the dynamics behavior of the actual structure, which greatly limits the application of TPMS structures in engineering. To break through the limitation, the present paper investigates the dynamic response behavior of Gyroid lattice sandwich plates under moving load. Based on the three-dimensional elasticity theory, the dynamic numerical model of Gyroid lattice sandwich plates under moving load is established by combining the spectral geometry method (SGM) and artificial virtual spring method. By employing the parameter inversion technique based on the dynamic properties, the equivalent material parameters of Gyroid lattice in terms of dynamics are introduced to directly identify, which effectively avoids the distortion of dynamic properties and the boundary non-periodic error that may be caused by the traditional static equivalent parameters. Finally, the effects of the lattice parameters and the type of moving load on the dynamic characteristics of the structure are systematically analyzed. Especially, the influence of lattice thickness ratio on the dynamic characteristics of the structure can provide an effective reference value for engineering design, thus realizing a wider application prospect of TPMS lattice sandwich plates in engineering.

三周期最小表面（TPMS）晶格结构，特别是陀螺结构，由于其优异的比强度、比刚度和可调的能量吸收特性，在轻量化多功能结构领域具有很大的潜力。然而，结构复杂的几何特性导致高精度动力学仿真的仿真复杂度巨大，现有等效参数获取方法难以准确表征实际结构的动力学行为，极大地限制了TPMS结构在工程中的应用。为了突破这一局限，本文研究了移动荷载作用下陀螺晶格夹层板的动力响应特性。基于三维弹性理论，结合谱几何方法（SGM）和人工虚拟弹簧方法，建立了移动载荷作用下陀螺晶格夹层板的动态数值模型。采用基于动态特性的参数反演技术，引入了Gyroid lattice的动力学等效材料参数直接辨识，有效避免了传统静态等效参数可能造成的动态特性畸变和边界非周期误差。最后，系统分析了点阵参数和运动荷载类型对结构动力特性的影响。特别是点阵厚度比对结构动力特性的影响可以为工程设计提供有效的参考价值，从而实现TPMS点阵夹芯板在工程上更广阔的应用前景。

Especially, the influence of lattice thickness ratio on the dynamic characteristics of the structure can provide an effective reference value for engineering design, thus realizing a wider application prospect of TPMS lattice sandwich plates in engineering.</div></div>","PeriodicalId":50866,"journal":{"name":"Advances in Engineering Software","volume":"211 ","pages":"Article 104038"},"PeriodicalIF":5.7,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145096629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents an efficient frequency domain cell vertex finite volume method (FD-CVFVM) to predict muffler transmission loss (TL). The heterogeneous Helmholtz equation is discretized based on FD-CVFVM. A control volume is constructed around each vertex. Acoustic pressure is stored at each mesh vertex. Shape functions are used to describe the acoustic pressure distribution. A calculation program implementing the FD-CVFVM is developed using the C++ language. The TL of a simple expansion chamber muffler, a resistive muffler, and a perforated resistive muffler are computed using different mesh models. The results are compared and analyzed against those obtained from commercial FEM software. The numerical results demonstrate that the FD-CVFVM predictions are in good agreement with those of the FEM results. It is found that the computational efficiency of the FD-CVFVM is significantly superior to that of commercial FEM software. The maximum computation time is reduced by approximately 78.2 %. An analysis of the sparsity pattern of the coefficient matrix is accomplished to reveal the reason of the superior computational speed over the commercial FEM software. This method is anticipated to offer a novel numerical approach for predicting muffler TL.

Rising incidence of train derailments and collisions underscores the urgent need for more effective passive energy‐absorbing systems. While conventional aluminum honeycomb devices achieve high specific energy absorption, they suffer from complex fabrication, require full replacement after minor impacts, and generate high rebound velocities that can exacerbate secondary damage. In this study, we propose a Multi-layered Nested Tubular Structure (MNTS)—an arrangement of adjustable square and circular thin-walled tubes—as an alternative absorber. A physics–based finite‐element (FE) model, incorporating material nonlinearity, simulates a lead‐car collision against a rigid wall and is validated against full-scale experiments (velocity: 8.357 m/s; mass: 54 t). The model accurately reproduces peak absorbed energy, average force response, displacement history, and rebound velocity. A parametric study of 144 FE simulations combined with response surface methodology identifies optimal wall‐thickness parameters (λ_s = 7.4 mm, λ_c = 18.6 mm), yielding a maximum energy absorption of 1.728 MJ (R_MSE = 0.0477 MJ, R² = 0.945). Building on these results, we develop a reduced‐order analytical model using logistic regression to relate train speed (5.0–9.0 m/s) to peak force, maximum displacement, and energy absorption, achieving an R² of 0.989 for displacement predictions. Validation against 41 additional FE runs confirms the analytical model’s accuracy while reducing computational cost by orders of magnitude. Compared with honeycomb absorbers, the MNTS matches energy-absorption efficiency yet significantly lowers peak impact forces and rebound velocities, thereby enhancing passenger safety. Together, the validated FE framework and its streamlined analytical counterpart constitute a rapid, practical design and assessment tool for train collision energy-absorption systems.

列车脱轨和碰撞事故的发生率不断上升，迫切需要更有效的被动吸能系统。虽然传统的铝蜂窝装置可以实现高比能吸收，但它们的制造复杂，在轻微撞击后需要完全更换，并且产生高回弹速度，可能会加剧二次损伤。在这项研究中，我们提出了一种多层嵌套管结构(MNTS) -一种可调节的方形和圆形薄壁管的排列-作为替代吸收器。基于物理的有限元（FE）模型，结合材料非线性，模拟了铅车与刚性墙壁的碰撞，并在全尺寸实验中进行了验证（速度：8.357 m/s；质量：54 t）。该模型准确地再现了峰值吸收能量、平均力响应、位移历史和回弹速度。结合响应面法对144个有限元模拟进行参数化研究，确定了最佳壁厚参数（λs = 7.4 mm, λc = 18.6 mm），最大吸能为1.728 MJ （RMSE = 0.0477 MJ, R²= 0.945）。在这些结果的基础上，我们开发了一个使用逻辑回归的降阶分析模型，将列车速度（5.0-9.0 m/s）与峰值力、最大位移和能量吸收联系起来，实现了位移预测的R²为0.989。对41个额外FE运行的验证证实了分析模型的准确性，同时降低了计算成本的数量级。与蜂窝式吸能器相比，MNTS在满足吸能效率的同时，显著降低了峰值冲击力和回弹速度，从而提高了乘客的安全性。经过验证的有限元框架和简化的分析框架共同构成了列车碰撞吸能系统快速实用的设计和评估工具。

The performance of road facility networks is directly related to the lives of citizens and therefore requires careful management. In particular, disasters such as earthquakes, which can rapidly degrade the performance of an entire road network, must be given significant consideration. This study proposes a seismic performance management system for road facility networks based on building information modeling (BIM). The proposed system integrates geographic information system (GIS), BIM, and structural analysis tools. To this end, the study first introduces the overall framework and the seismic performance assessment methodology. The framework is developed to support the generation, analysis, and updating of network-level BIM. To generate the BIM for a road facility network, an algorithm is developed that automatically generates terrain surfaces and road facility objects by linking GIS data. In addition, a method for extracting and transforming object information from the BIM is established to enable BIM-based numerical modeling and integration with analysis tools. Seismic performance is evaluated by separating structural and functional performance at both the individual and network levels. To demonstrate the feasibility and applicability of the proposed framework, we applied the proposed framework to Gyeongju, an area damaged by seismic events in South Korea, to generate the network BIM and perform seismic simulations. Furthermore, the seismic simulation results are updated in the network BIM for archiving and visualization. The results show that the proposed framework is successfully implemented for the road facility network used in the case study.

道路设施网络的性能直接关系到市民的生活，因此需要精心管理。特别是像地震这样的灾害，它可以迅速降低整个道路网络的性能，必须给予重要的考虑。本文提出了一种基于建筑信息模型（BIM）的道路设施网络抗震性能管理系统。该系统集成了地理信息系统（GIS）、BIM和结构分析工具。为此，本研究首先介绍了总体框架和抗震性能评价方法。开发该框架是为了支持网络级BIM的生成、分析和更新。为了生成道路设施网络的BIM，开发了一种通过链接GIS数据自动生成地形表面和道路设施对象的算法。此外，建立了从BIM中提取和转换对象信息的方法，实现了基于BIM的数值建模和与分析工具的集成。抗震性能是通过在个体和网络两个层面上分离结构和功能性能来评估的。为了证明所提出的框架的可行性和适用性，我们将所提出的框架应用于庆州，这是韩国遭受地震事件破坏的地区，以生成网络BIM并进行地震模拟。此外，地震模拟结果在网络BIM中更新，便于存档和可视化。结果表明，该框架在道路设施网络中得到了成功的应用。
