Analysis and Optimization Design on K&C of Non-independent Front Suspension for a Medium Bus

利用Adams/Car软件建立某中型客车非独立前悬架仿真模型,采用平行轮跳工况对客车前悬架进行K&C特性仿真分析,使用Insight模块对悬架硬点进行灵敏度分析,并对影响系数大的硬点坐标进行优化设计,为改进悬架系统性能提供参考。

Adam^^Car is used to establish simulation model for a medium bus non-independent front sus-pension. Parallel wheel bounce condition is used to do K＆C characteristics simulation analysis. Adam^^In-sight module is applied to analyze sensitivity of suspension hard points,and to do optimal design on the hard points of big influence coefficient. This paper provides reference for improving the performance of suspen-sion system.
