基于虚拟样机的空气悬架大客车平顺性仿真分析

摘要

Taking an air suspension coach as a researched object, the author introduces the theory of multi-body system dynamics, establishes the virtual prototype of a type of a coach equipped with air suspension, and the simulation of the comfortable capability is carried out. Then the acceleration value of some locations on the body is tested to prove the simulation correct.%以空气悬架大客车为研究对象,采用多体系统动力学的理论方法,建立某型客车的虚拟样机仿真模型,并进行平顺性仿真。最后测试车身上相应位置的加速度值,对模型进行验证。
