基于ADAMS和MATLAB的主动悬架控制联合仿真研究

Co-simulating Active Suspension System Based on ADAMS and MATLAB

汽车悬架的动力学性能直接影响到汽车的平顺性和操纵稳定性,利用ADAMS软件建立四分之一汽车主动悬架模型,通过MATLAB/Simulink求解主动悬架线性最优控制策略,并对其进行联合仿真[1]。结果表明基于最优控制的汽车主动悬架减小了车辆振动,提高了车辆的平顺性和安全性。为汽车悬架减振性能的开发设计提供了一种有效的方法。

The vehicle’s suspension directly affects the vehicle behaviour on the road,both for the riding comfort and the controlling stability.The application of ADAMS built one-fouth’s active suspension model,a linear optimal controller was designed for active suspension system and worked out by means of MATLAB/Simulink.And the controlling strategy was co-simulated.The results show that the optimal control active suspension reduces the vehicle’s vibration and improves the riding comfort characteristics.
