摘要/Abstract

摘要： 基于汽车独立悬架后桥(ISRA)悬置系统6自由度振动分析模型，分别给出了其固有频率和能量分布的设计要求及其在零转动、静态转动和动态转动工况下的设计要求，并提出了ISRA悬置系统的优化设计方法。在绕扭矩轴的扭矩激励下，优化得到各悬置静刚度的设计值，分别计算了ISRA悬置系统的固有频率和能量分布，零转动工况下后桥质心、质心坐标系Ya轴上一点的位移及各悬置的垂向位移和垂向动反力，静态转动工况下后桥质心和扭矩轴上一点的位移。研究结果表明：利用所提方法设计的ISRA悬置系统可以满足设计要求，对后桥悬置系统设计具有参考作用。

Abstract: Based on a six degrees of freedom model of a vehicle ISRA mounting system, the design requirements of natural frequencies and energy distributions of the model, zero-roll condition, static roll condition and dynamic roll condition were presented, respectively.The optimization and design methods for the ISRA mounting system were proposed.Under the torque excitation around torque axis, the designed static stiffness of each mount were optimized.Natural frequencies and energy distributions of the ISRA mounting system were calculated.Under zero-roll conditions, the displacements of centriod of the rear axle, one point on the Ya-axis of the centroid coordinate system, the vertical displacements and vertical dynamic reaction forces of each mount were also calculated, respectively.Under static roll conditions, the displacement of centriod of the rear axle, one point on the torque axis were calculated, respectively.The results show that the ISRA mounting system designed by the proposed method may satisfy the design requirements, which may provide references for the design of rear axle mounting system.

Key words: independent suspension rear axle（ISRA） mounting system, stiffness, design requirement, design method
