客车空气悬架的建模与K&C特性分析

Air Suspension Modeling and K&C Characteristics Analysis

根据某新型大客车的设计要求,运用刚柔耦合的建模方法对客车关键部件进行了柔性处理,建立了前悬架的刚柔耦合的Adams多体动力学模型,并对悬架系统进行了动力学仿真分析。结合理论分析得出该悬架的K&C(Kinematics&Compliance)特性相关数据,以及悬架在运动过程中的参数变化范围,为后期的调校和生产提供了可靠的理论数据。

According to the design requirements of a new bus type, the key components was processed in flexible way by using modeling method, and the front suspension system rigid-flexible coupling Adams multi-body dynamics model to the new developing coach was established. And we also did the dynamic simulation analysis of the suspension system, and obtained the suspension relevant data of K＆C characteristics and got the rang of parameter changes of the suspension in the process of movement, which provides reliable theoretical data for later calibration and production.
