摘　　要：为提升汽车行驶过程中的舒适度,需保证汽车具有较好的隔振性能,因此,本文以汽车发动机悬置系统为例,研究汽车发动机悬置系统的隔振分析及优化设计。以该发动机悬置系统的实际参数为依据,进行汽车发动机悬置系统隔振性能解耦分析,并通过ADAMS软件,构建悬置系统仿真模型,获取悬置系统不同方向的解耦率结果,确定悬置系统隔振性能情况;并针对分析结果进行悬置系统设计优化。通过优化后的动刚度分析结果可知,优化设计后,发动机悬置系统的隔振性能满足标准需求。In order to improve the comfort of a car during driving,it is necessary to ensure that the car has good vibration isolation performance.Therefore,this article takes a car engine mounting system produced by a certain company as an example to study the vibration isolation analysis and optimization design of the car engine mounting system.Based on the actual parameters of the engine mounting system,decoupling analysis of the vibration isolation performance of the automotive engine mounting system is carried out.Through ADAMS software,a simulation model of the mounting system is constructed to obtain the decoupling rate results in different directions of the mounting system and determine the vibration isolation performance of the mounting system;And optimize the suspension system design based on the analysis results.Through the optimized dynamic stiffness analysis results,it can be seen that the vibration isolation performance of the engine mounting system meets the standard requirements after the optimized design.
