摘要
以麦弗逊式独立悬架汽车为研究对象,依据多体系统动力学理论,利用ADAMS/Car建立76自由度整车模型,并利用ADAMS/Insight对麦弗逊前悬架进行优化设计.仿真实验表明:采用优化后的前悬架系统,可以使整车的高速摆振幅值明显减小,而且使整车操纵稳定性得以提高.
An automobile model of 76 degrees of freedom was established with Macpherson independent suspension using ADAMS/Car by multi-body system dynamics theory. The optimal design of Macpherson suspension was completed by ADAMS/Insight. The result shows that the front wheel shimmy angle at high speed was decreased obviously and the steady state steering character was improved through the optimal design.
