考虑整车的刚柔多体全浮式驾驶室悬置系统参数优化设计

Parameterized Optimal Design of Fully-Float Cab Suspension System of Commercial Vehicles Based on the Theory of Rigid-Flexible Dynamics

在考虑车架柔性的基础上研究商用车驾驶室悬置参数优化问题。建立了基于整车的刚柔多体全浮式驾驶室悬置系统参数化模型,对驾驶室悬置系统和底盘主悬置系统进行参数匹配优化设计,提高了整车系统的平顺性。

This paper studies parameterized optimal design of the cab suspension system of commercial vehicles considering the frame flexibility. The rigid-flexible multi-body model for vibration simulation of whole vehicles is established. The parameter-matching optimal design of the cab suspension system and the flex-frame suspension system is done. As a result, the smoothness of vehicles is improved.
