To meet our Net Zero commitments, the past decade has seen a dramatic increase in wind power, with hundreds of thousands of wind turbines already in place. Many studies have focused on the environmental impact of windfarms; however, wind turbine-induced ground seismic vibrations have received less attention. Prior seismic observations near wind turbines show apparently contradictory spatio-temporal noise patterns and complex relationships to operational parameters. Here, we investigate these contradictions, categorizing seismic observations from wind farms worldwide, and explain the causes for this variation. We link the ground seismic response to the fundamentals of wind, the structural response of wind turbines, and the interactions of their foundations with variable geology. We summarise these approaches and discuss potential implementation in noise management, alongside noise suppression technologies. We finally explore the use of wind turbine noise as a seismic source to potentially monitor the structural health of wind turbine structures, and the subsurface. The latter is highly relevant to measurement, monitoring and verification of CO₂ and H₂ storage, where cost-effective and long-term monitoring solutions are necessary.

为了实现我们的“净零排放”承诺，过去十年风力发电大幅增长，已有数十万台风力涡轮机投入使用。许多研究都集中在风电场对环境的影响上；然而，风力涡轮机引起的地面地震振动受到的关注较少。先前在风力涡轮机附近的地震观测显示出明显矛盾的时空噪声模式和与运行参数的复杂关系。在这里，我们调查了这些矛盾，对世界各地风电场的地震观测进行了分类，并解释了这种差异的原因。我们将地面地震反应与风的基本原理、风力涡轮机的结构反应以及它们的基础与可变地质的相互作用联系起来。我们总结了这些方法，并讨论了在噪声管理和噪声抑制技术方面的潜在实施。我们最后探讨了利用风力涡轮机噪声作为震源来潜在地监测风力涡轮机结构和地下结构的健康状况。后者与二氧化碳和氢气储存的测量、监测和验证高度相关，需要具有成本效益的长期监测解决方案。

Finite element plate and shell formulations are ubiquitous in structural analysis for modeling all kinds of slender structures, both for static and dynamic analyses. The latter are particularly challenging as the high order nature of the underlying partial differential equations and the slenderness of the structures all impose a stringent constraint on the critical time step in explicit dynamics. Unfortunately, badly cut elements in immersed finite element discretizations further aggravate the issue. While lumping the mass matrix often increases the critical time step, it might also trigger spurious oscillations in the approximate solution thereby compromising the numerical solution. In this article, we extend our previous work in [1] to allow stable immersogeometric analysis of plate and shell problems with lumped mass matrices. This technique is based on polynomial extensions and restores a level of accuracy comparable to boundary-fitted discretizations.

在各种细长结构的静力和动力分析中，板壳有限元公式在结构分析中无处不在。后者尤其具有挑战性，因为潜在的偏微分方程的高阶性质和结构的长细性都对显式动力学中的关键时间步施加了严格的约束。不幸的是，浸入式有限元离散中严重切割的单元进一步加剧了这一问题。虽然集总质量矩阵通常会增加临界时间步长，但它也可能在近似解中触发伪振荡，从而损害数值解。在本文中，我们扩展了之前在[1]中的工作，以允许具有集中质量矩阵的板壳问题的稳定浸入式几何分析。该技术基于多项式扩展，恢复了与边界拟合离散化相当的精度水平。

Beams with time-varying added mass are prone to vibrations due to external disturbances, whose vibration suppression is challenging because of the time-varying characteristics of the system. In this paper, an adaptive method for three-dimensional (3-D) vibration mitigation of beams with time-varying added mass is proposed. First, the dynamic equations of the beam with time-varying added mass incorporating geometric nonlinearity are derived using Lagrange’s equations. Then, the proposed method is applied to the motion of the flywheel assembly installed on the beam. Theoretical results under free and forced vibration confirm the feasibility of the proposed method for 3-D vibration mitigation of the beam with added mass exhibiting different time-varying characteristics, even in the presence of nonlinear vibrations. Moreover, experimental results validate the effectiveness of the proposed method. Compared to the existing methods, the proposed method does not require prior knowledge of the parameters of the beam with time-varying added mass. It is not constrained by the bounds of parameter variations or the forms of these variations. Thus, the proposed method offers good adaptability and strong robustness for 3-D vibration suppression of beams with time-varying added mass.

具有时变附加质量的梁容易受到外界干扰而产生振动，由于系统的时变特性，对其振动抑制具有挑战性。本文提出了一种具有时变附加质量的梁的三维自适应减振方法。首先，利用拉格朗日方程推导了含几何非线性的时变附加质量梁的动力学方程。然后，将该方法应用于安装在梁上的飞轮组件的运动。在自由振动和强迫振动下的理论结果证实了所提出的方法对于具有不同时变特性的附加质量梁的三维振动抑制的可行性，即使存在非线性振动。实验结果验证了该方法的有效性。与现有方法相比，该方法不需要事先知道随时间变化的附加质量梁的参数。它不受参数变化的边界或这些变化的形式的约束。因此，该方法对时变附加质量梁的三维振动抑制具有较好的适应性和较强的鲁棒性。

A novel approach for identifying system poles using multi-reference transmissibility functions based on frequency shifts 一种基于频移的多参考传递率函数识别系统极点的新方法

System pole identification using Operational Modal Analysis (OMA) methods is often subject to significant estimation errors. A key source of these inaccuracies is the presence of non-periodic frequency components in short-domain earthquake records, which amplify variance errors, especially in higher modes. Additionally, violations of Fast Fourier Transform (FFT) assumptions on discrete signals introduce bias errors across all structural modes. To overcome these limitations, this study introduces a novel method called Multi-Reference Transmissibility Complex Frequency (MTCF). This approach defines new transmissibility matrices in the frequency domain using the z-transform framework. By integrating both forward and backward frequency shifts into the transmissibility functions, MTCF effectively reduces variance errors, particularly in higher modes, while also minimizing bias across all modes. The method's performance is evaluated using a four-degree-of-freedom reinforced concrete frame subjected to three different earthquake records under varying loading conditions. Results show that natural frequencies and mode shapes and damping ratios of higher modes are identified with accuracy comparable to lower modes, eliminating the need to decompose frequency responses into single-frequency components for damping estimation. Unlike OMA-based techniques, where higher modes often remain undetected or exhibit larger errors, the MTCF method Mitigates spectral leakage and numerical dispersion. This enables accurate and robust identification of all modal parameters, regardless of the structure’s degrees of freedom or the complexity of external excitations.

使用运维模态分析（OMA）方法进行系统极点辨识时，往往存在较大的估计误差。这些不准确的一个关键来源是在短域地震记录中存在的非周期频率分量，它放大了方差误差，特别是在更高的模态中。此外，对离散信号的快速傅里叶变换（FFT）假设的违反会在所有结构模式中引入偏置误差。为了克服这些限制，本研究引入了一种称为多参考传输率复频率（MTCF）的新方法。该方法使用z变换框架在频域定义新的透射率矩阵。通过将前向和后向频移整合到透射率函数中，MTCF有效地减少了方差误差，特别是在更高的模式下，同时还最小化了所有模式的偏差。采用四自由度钢筋混凝土框架在不同荷载条件下承受三种不同地震记录，对该方法的性能进行了评估。结果表明，高阶模态的固有频率、模态振型和阻尼比的识别精度与低阶模态相当，无需将频率响应分解为单频分量进行阻尼估计。与基于oma的技术不同，基于oma的技术通常无法检测到更高的模式或显示更大的误差，MTCF方法减轻了频谱泄漏和数值色散。这使得所有模态参数的准确和稳健的识别，而不管结构的自由度或外部激励的复杂性。

This paper presents a solution to the limitations of traditional vibration control methods, which often depend on precise structural parameters and mathematical models, leading to poor performance under real-world uncertainties and nonlinearities. The study introduces an vibration control system based on adaptive Active Rotary Inertia Driver (ARID) systems. This system integrates three key components: fractional-order dynamic fuzzy modeling for online system identification, a self-structuring Type-3 Fuzzy Logic System (T3-FLS) with non-singleton fuzzification to handle sensor noise and uncertainties, and an adaptive compensator based on the H_∞ theorem to ensure robustness against disturbances and parameter variations. The T3-FLS employs a new self-structuring algorithm that autonomously optimizes rule databases, membership functions, and parameters in response to dynamic conditions, addressing a gap in the existing literature regarding self-structuring mechanisms for T3-FLSs in vibration control applications. Experimental/simulation validation demonstrates the superiority of the proposed system compared to conventional methods. In experiments/simulations, the proposed algorithm achieved a peak angle of 0.009/0.005 rad and an RMS of 91.5%/95.7%, showing significant improvements over conventional methods, which only achieved 0.7%/1.4% and 0.8% /2.3% under perturbed dynamics (see the video of implementation at https://youtu.be/OWS8Ums95sQ.

传统的振动控制方法往往依赖于精确的结构参数和数学模型，导致在现实世界的不确定性和非线性下性能不佳，本文提出了一种解决方法。介绍了一种基于自适应主动旋转惯量驱动（ARID）系统的振动控制系统。该系统集成了三个关键组件：用于在线系统辨识的分数阶动态模糊建模，具有非单态模糊化的自结构3型模糊逻辑系统（T3-FLS），用于处理传感器噪声和不确定性，以及基于H∞定理的自适应补偿器，以确保对干扰和参数变化的鲁棒性。T3-FLS采用了一种新的自结构算法，可以根据动态条件自主优化规则数据库、隶属函数和参数，解决了现有文献中关于T3-FLS在振动控制应用中的自结构机制的空白。实验/仿真验证表明，与传统方法相比，所提出的系统具有优越性。在实验/仿真中，该算法的峰值角为0.009/0.005 rad， RMS为91.5%/95.7%，与传统方法相比有了显著的改进，传统方法在摄动动态下仅能达到0.7%/1.4%和0.8% /2.3%（参见https://youtu.be/OWS8Ums95sQ的实现视频）。

A reduced order modeling strategy for nonlinear elasto-dynamic systems with cyclic symmetry in rolling contact 滚动接触循环对称非线性弹性动力系统的降阶建模策略

Rolling contact is frequently modeled for simulating engineering systems (e.g. tires or bearings). When accounting for geometric and material nonlinearity, model order reduction (MOR) becomes essential to reduce the computational costs of dynamic simulations. Addressing nonlinear systems with distributed nonlinearities in combination with large areas of rough surface contact and a dynamically changing active set presents a challenge for state-of-the-art MOR methods. Therefore, a tailored a-priori MOR approach to address large deformation rolling contact for cyclically symmetric systems is presented.

We propose a novel two-step, projection-based nonlinear MOR for rolling contact. In the first step, the reduction basis based on the Multi Expansion Modal method is transformed to a Generalized Component Mode Synthesis framework to achieve rotational invariance of the basis. To capture the nonlinear variations due to rotation and the resulting change of the active contact area, an interpolation approach is employed to adjust the basis accordingly. In the second step, the Energy Conserving Sampling and Weighting hyper reduction parameters are also adapted through interpolation.

The proposed method is validated for the case of a Grosch wheel rotating on a smooth surface and a tire rotating on a rough road. In both cases, the reduced-order model accurately replicates the full-order model’s dynamic behavior. While the speedup is limited in the Grosch wheel case, significant speedup is achieved for a nonlinear tire model with a maximum speedup factor of 20.

滚动接触经常用于模拟工程系统（如轮胎或轴承）。当考虑几何和材料非线性时，模型降阶（MOR）对于降低动态仿真的计算成本至关重要。求解具有大面积粗糙表面接触和动态变化的活动集的分布非线性非线性系统是目前最先进的MOR方法面临的挑战。因此，提出了一种针对循环对称系统大变形滚动接触的定制先验MOR方法。提出了一种新的基于投影的两步非线性滚动接触MOR算法。首先，将基于多展开式模态方法的约简基转化为广义模态综合框架，实现基的旋转不变性；为了捕捉由于旋转引起的非线性变化和由此引起的主动接触面积的变化，采用插值方法对基进行相应的调整。第二步，通过插值调整节能采样和加权超约化参数。针对格罗施车轮在光滑路面上的旋转和轮胎在粗糙路面上的旋转进行了验证。在这两种情况下，降阶模型都精确地复制了全阶模型的动态行为。而加速是有限的，在格罗施车轮情况下，显著加速实现了非线性轮胎模型的最大加速系数为20。

This study investigates the dynamic response of linear-elastic and elastic-plastic Single Degree of Freedom (SDOF) systems subjected to two consecutive triangular pulse loads, a scenario relevant to blast-resistant design yet often neglected in conventional analysis. The concept of an amplification factor (AMF) is introduced to quantify the increase in maximum displacement relative to a single load. The response is analyzed across three classical regimes: impulsive, dynamic, and quasi-static, highlighting the dominant role of delay time between pulses in shaping the structural response. Closed-form expressions are derived for AMF in both impulsive and quasi-static limits, and analytical relationships are established between the amplification factor and the asymptotic bounds of Pressure-Impulse (P-I) diagrams. Parametric studies show that while the impulse and peak pressure ratios (η and κ) set the amplification bounds, the delay time (t_h) critically governs the maximum response. In the elastic-plastic case, three distinct regimes are identified based on the yielding state at the time of the second load, and closed-form expressions for the asymptotes are derived. The findings offer both fundamental insight and practical tools for constructing conservative failure envelopes without the need for extensive numerical simulations.

本文研究了线弹性和弹塑性单自由度（SDOF）系统在两个连续三角形脉冲载荷作用下的动态响应，这是一种与防爆设计相关但在传统分析中经常被忽视的情况。引入了放大因子（AMF）的概念来量化相对于单个负载的最大位移的增加。分析了三种经典状态下的响应：脉冲、动态和准静态，强调了脉冲间延迟时间在形成结构响应中的主导作用。导出了AMF在脉冲极限和准静态极限下的封闭表达式，建立了放大因子与压力-脉冲图渐近界之间的解析关系。参数研究表明，当脉冲和峰值压力比（η和κ）设定放大边界时，延迟时间（th）关键地控制最大响应。在弹塑性情况下，根据第二次加载时的屈服状态识别出三种不同的状态，并推导出渐近线的封闭表达式。这些发现为构建保守失效包络层提供了基本的见解和实用的工具，而无需进行大量的数值模拟。

The findings offer both fundamental insight and practical tools for constructing conservative failure envelopes without the need for extensive numerical simulations.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"626 ","pages":"Article 119631"},"PeriodicalIF":4.9,"publicationDate":"2026-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145977915","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}

Linear quadratic regulator (LQR) control has been widely demonstrated to be suitable and effective for active base-isolated buildings. However, its application to the buildings equipped with nonlinear dampers remains challenging due to the theoretical and design complexity. This paper presents a simple response-spectra-based design method for LQR control of active base-isolated buildings with bilinear oil dampers (BODs). First, a gain-scheduling-based LQR (GSLQR) control algorithm is presented to accommodate BODs. The GSLQR controller is defined as a total controller composed of BODs as the passive part and a gain-scheduling (GS) controller as the active part. This separates BODs from the plant, thereby transforming the control of a nonlinear system into the control of a linear system. We optimize the total control force using an LQR algorithm considering acceleration, velocity, and displacement. Then, a response-spectra-based design method is presented. We construct an equivalent passive model (EPM) of the system, which enables the estimation of maximum responses on the response spectra. Moreover, a control-force spectrum is presented to estimate the maximum required active control force. Finally, a design procedure is provided and an example is given to show the feasibility of the design method. The results indicate that this method extends LQR control to buildings with BODs and determines the design parameters from the spectra to meet the design requirements, without relying on simulations or trial-and-error procedures. This presents a promising strategy for designing active control systems in buildings equipped with nonlinear dampers.

线性二次型调节器（LQR）控制已被广泛证明是一种适用于主动隔基建筑的有效控制方法。然而，由于理论和设计的复杂性，将其应用于具有非线性阻尼器的建筑物仍然具有挑战性。提出了一种基于响应谱的双线性油阻尼器主动隔基结构LQR控制的简单设计方法。首先，提出了一种基于增益调度的LQR （GSLQR）控制算法。GSLQR控制器被定义为由bod作为被动部分和增益调度（GS）控制器作为主动部分组成的总控制器。这将bod从工厂中分离出来，从而将非线性系统的控制转变为线性系统的控制。我们使用考虑加速度、速度和位移的LQR算法来优化总控制力。然后，提出了一种基于响应谱的设计方法。我们建立了系统的等效被动模型（EPM），使响应谱上的最大响应估计成为可能。此外，提出了一种控制力谱来估计所需的最大主动控制力。最后给出了设计步骤，并通过实例说明了设计方法的可行性。结果表明，该方法将LQR控制扩展到具有bod的建筑物，并从光谱中确定设计参数以满足设计要求，而不依赖于模拟或试错过程。这为设计具有非线性阻尼器的建筑物的主动控制系统提供了一种很有前途的策略。

Nonlinear acoustic meta-materials/structures (NAMs) hold great promise for ultra-low and ultra-broadband vibration suppression through chaotic band mechanisms, but at the expense of compromising the original bandgap benefits. To concurrently harness the benefits arising from both bandgaps and chaotic passbands, we propose a dedicated design paradigm in which both linear and nonlinear oscillators are integrated in meta-plates. Harmonic balance method and time-domain integration are utilized to compute the system responses and evaluate the performances of two types of meta-plates. Type I design leverages the complementary benefits of linear acoustic meta-materials/structures (LAMs) and NAMs. The design entails the stability of the bandgap, in which additional 17 dB improvement is achieved over traditional NAMs, while maintaining a stable chaotic band. Type II extends the Type I design, elucidating the influence of nonlinearity location, linear stiffness and damping. Based on the insights gained, broadband vibration suppression has seen a significant extension into the lower frequency range, along with a notable improvement in vibration suppression effectiveness. Our concept is demonstrated experimentally on a meta-plate consisting of linear and vibro-impact nonlinear oscillators. The study alludes to a new route for designing high-performance meta-structures in views of structural vibration control.

非线性声学元材料/结构（NAMs）通过混沌带机制抑制超低和超宽带振动，但以牺牲原有带隙优势为代价。为了同时利用带隙和混沌通带带来的好处，我们提出了一个专门的设计范例，其中线性和非线性振荡器都集成在元板中。利用谐波平衡法和时域积分法计算了两种元板的系统响应，并对其性能进行了评价。I型设计利用线性声学超材料/结构（lam）和NAMs的互补优势。该设计需要稳定的带隙，在保持稳定的混沌带的同时，比传统的NAMs实现了额外17 dB的改进。II型扩展了I型设计，阐明了非线性位置、线性刚度和阻尼的影响。基于所获得的见解，宽带振动抑制已经显著扩展到较低的频率范围，同时振动抑制效果也得到了显着改善。我们的概念在由线性和振动冲击非线性振荡器组成的元板上得到了实验证明。从结构振动控制的角度出发，为设计高性能元结构提供了一条新的途径。
