摘　　要：为解决乘用车常用的麦弗逊悬架在开发过程中出现的性能指标计算精度差、底盘调校效率低等问题,分析了麦弗逊悬架减振器侧向力成因及对车辆性能的影响。采用虚拟衬套法构建了柔性减振器模型,并在几款车型上进行动力学性能开发验证,结果表明该方法提升了麦弗逊悬架及整车性能的预测精度,有利于前期的性能设计和后期的底盘调校。总结了柔性减振器建模及在车型应用中的经验。In order to solve the development problems of passenger car Mac Pherson suspension, i.e. poor accuracy of performance index calculation, low efficiency of chassis tuning, etc., the cause of shock absorber＇s lateral force and its effects on vehicle performance are analyzed. The flexible shock absorber model is built through the method of virtual bushing. The model is verified in the dynamic performance development of several cars. The results show that the proposed method improves the performance prediction precision of Mcpherson suspension and vehicle. It＇s conducive to performance design and chassis tuning. The experiences in flexible shock absorber modeling and application are summarized.
