摘要

集振动控制和能量收集功能于一体的悬挂系统被称为双功能悬挂系统(DFS)。双功能悬挂系统的主要目标包括结构轻巧、输出力大、阻尼可调范围广以及能耗最小。为了优化结合到 DFS 中的线性电机和磁流变阻尼器(MRD),设计了一种多目标粒子群优化(PSO)算法,强调主要目标和次要目标,以提高 DFS 的整体性能。建立了 DFS 的综合数学模型,并在建模后对 DFS 的结构参数进行了细致分析。根据分析结果,划定了主要和辅助优化目标,并采用 PSO 对 DFS 结构进行细化。随后,利用模糊定理原则对优化过程中得出的帕累托解决方案集进行了明智的选择。结果表明,在悬架包装尺寸和总体能耗不变的约束条件下,优化后的悬架系统与优化前的状态相比,输出力增加了 50%,可调阻尼范围扩大了 30%,推力波纹减少了 39%。

Optimization of dual-function suspension structures using particle swarm optimization approaches
The suspension system integrating both vibration control and energy harvesting capabilities is denoted as Dual-function Suspension (DFS). The principal objectives for DFS encompass lightweight structure, high output force, extensive adjustability in damping, and minimized energy consumption. In pursuit of optimizing the linear motor and magnetorheological damper (MRD) amalgamated into the DFS, a multi-objective Particle Swarm Optimization (PSO) algorithm is conceived, emphasizing primary and secondary objectives to enhance the holistic performance of the DFS. A comprehensive mathematical model of the DFS is established, and subsequent to this modeling, the structural parameters of DFS are meticulously analyzed. Drawing upon the insights from this analysis, primary and supplementary optimization objectives are delineated, employing PSO for the refinement of the DFS structure. Following this, the Pareto solution set, derived from the optimization process, is judiciously selected utilizing fuzzy theorem principles. The outcomes reveal that, under the constraints of unaltered suspension packaging dimensions and overall energy consumption, the optimized suspension system manifests a 50% augmentation in output force, a 30% expansion in adjustable damping range, and a 39% reduction in thrust ripple compared to its pre-optimized state.
