摘要

为了应对选定的非气动车轮（NPW）质量和垂直刚度增加所引起的车辆动态性能下降，本研究提出了一种基于动态振动吸收器（DVA）的新型减振系统（NVDS）。首先，建立了包含 NPW 有效垂直刚度的四分之一车辆模型。然后，从多方面研究了增加车轮质量和刚度对车辆动态性能的影响。为了改善带有 NPW 的车辆的操纵性能，提出了一种基于 DVA 的 NVDS。研究了操控性能和乘坐舒适性对参数变化的敏感性，以确定参数的选择范围。采用多目标遗传算法（GA）确定 NVDS 的最优参数。在不同道路激励下获得的结果表明，所提出的 NVDS 可以显著提高车辆的操控性能和乘坐舒适性。

Design and Optimization of a New Vibration Damping System for the Driving Characteristics of the Selected Case of Replacing Pneumatic Wheels with Nonpneumatic Wheels

To cope with the deterioration of vehicle dynamic performance induced by the increased mass and vertical stiffness of selected nonpneumatic wheels (NPWs), this study proposed a new vibration damping system (NVDS) based on the dynamic vibration absorber (DVA). First, a quarter-vehicle model containing the effective vertical stiffness of the NPW is established. Then, the effect of increased wheel mass and stiffness on vehicle dynamic performance is investigated from various aspects. To improve the handling performance of the vehicle with NPWs, a DVA-based NVDS is proposed. The sensitivities of handling performance and ride comfort to parameter changes are investigated to determine the selection range of parameters. The multiobjective genetic algorithm (GA) is employed to determine the optimal parameters of NVDS. The results obtained under different road excitations indicate that the proposed NVDS can significantly enhance the handling performance and ride comfort of the vehicle.
