装备可控悬架的整车虚拟样机协同仿真

Co-simulation of Virtual Prototype Automobiles with Controllable Suspensions

可控悬架作为现代车辆的关键部件之一,对车辆的平顺性有重要影响。本文基于ADAMS和MATLAB/SIM-ULINK分别建立了装备可控悬架的整车动力学模型及整车半主动悬架控制模型。通过两个模型联合对某装备可控悬架的整车进行了仿真分析,结果表明半主动悬架可减小车辆振动,改善车辆的平顺性。该方法避免了建立整车动力学方程及推导传递函数,为复杂机械系统的控制与仿真提供了新思路。

As one of the most important parts of a modem automobile, a controllable suspensions has great influence on the smoothness of automibiles. This paper established a dynamic control model by combining the following two models. One is the full-car dynamic model using ADAMS and the other is the semi-active suspension control model MTLAB/Simulink. The result shows that the semi-active suspension can reduce the vibration of the automobile and thus improve its smoothness. The method avoid using dynamic equations and transfer functions, offering a new way of thinking for the control and simulation of complicated mechanical systems.
