摘要: 为实现车辆动力学的高效精确求解,将多体动力学粘结算法引入动力学仿真求解过程中.通过对多刚体三摆机构及含有柔体部件的四杆机构进行拓扑解析、子系统分解与粘结,对粘结算法的理论与具体求解过程进行了系统说明; 然后以某电动汽车为对象,运用粘结算法建立了包含前后悬架、车身及车轮在内的多体仿真模型,将整车系统分解为4 个独立子系统; 最后运用Matlab 实现了整车的建模与仿真,结果验证了文中方法的可行性.

Abstract:

Investigated in this paper is a gluing algorithm for the multi-body dynamic simulation,which helps to implement effective and accurate dynamic analysis of vehicles. In the investigation,first,the topologies of the multibody triple-pendulum system and the quadruple-pendulum system with elastic parts are analyzed,decomposed and glued,through which the theory of the gluing algorithm and the corresponding solving process are systematically illustrated. Then,the multi-body dynamic simulation model of an electric vehicle,which takes the front suspension,the rear suspension,the vehicle body and the wheel as four individual subsystems,is established based on the gluing algorithm. Finally,the modeling and simulation of the whole vehicle is implemented with Matlab. The results show that the proposed gluing algorithm-based method is feasible.
