摘　　要：以ADAMS/CAR二次开发模块为平台,建立了国产某小型客车虚拟样机的多体系统动力学仿真模型。按照国家有关整车平顺性的试验评价方法和标准,进行了整车平顺性脉冲输入和随机输入行驶仿真试验分析。对比实车测试结果,主要评价指标加权振级的最大仿真误差小于5%,即仿真结果具有较高的可信度,说明在车辆设计阶段,利用此二次开发模块可对其平顺性进行有效的分析和评估。On the platform of the ADAMS/CAR secondary development module,the MB dynamics simulation model of the virtual prototype of a domestic light bus has been created,According to our national relative standards and evaluation criteria of vehicle ride performance test methods,vehicle ride performance simulation tests and analysis with pulse inputs and random inputs are carried out.Compared with results of tests,the max.simulatin error of the main evaluation in dexes with weighted vibration level is less than 5 % ,that is,the simulation results have a high confidence.Therefore ADAMS/CAR secondary development module can be used to analyze and evaluate ride performance during vehicle design phase.
