【摘要】 基于悬架系统对汽车舒适性和操稳性的重要影响,本文利用ADAMS仿真软件对麦弗逊式独立悬架进行动力学仿真与优化。根据麦弗逊式独立悬架的CATIA模型及硬点,首先在ADAMS/Car模块中搭建悬架的物理模型,然后进行仿真分析,再利用后处理模块ADAMS/Post Processor模块查看仿真结果,得到有关悬架性能的曲线,包括四轮定位参数曲线,并对分析不合理的车轮前束角通过ADAMS/Insight模块进行了进一步的优化,最终明显提高了汽车的舒适性和操稳性。更多还原

【Abstract】 In view of the important influence of suspension system on the comfort and stability of vehicle, simulation analysis and optimization of Mac Pherson suspension system are carried out by ADAMS. Firstly, based on the CATIA model and the hard points of Mac Pherson independent suspension, the model of Mac Pherson independent suspension is built by the ADAMS/Car. Then the simulation analysis is carried out and the simulation results are gained by the ADAMS/Postprocessor. The results get the suspension performance curve, including the four-wheel positioning parameter curve.Finally, the experiments prove obviously on improving the comfort and stability of vehicle through analyzing the unreasonable wheel toe Angle by ADAMS/ Insight.更多还原
