摘要
针对公路车辆对道路破坏性的问题 ,在主动悬架设计中采用联合仿真的方法 ,对车辆系统采用基于多体系统 (MBS)动力学理论的“功能化虚拟样机”(FVP)技术和ADAMS软件进行建模 ,对主动悬架控制系统采用计算机辅助控制系统设计 (CACSD)技术和Matlab软件进行建模 ,继而将二者结合起来进行联合仿真。采用上述方法进行车辆—道路相互作用的研究和主动悬架系统的设计是方便有效的 ;所设计出的车辆主动悬架系统能够明显降低车辆对道路动态作用力的水平 ,从而延长道路疲劳破坏应变循环次数 。
The research was focused on using active suspension for reducing the vehicle-generated road damage. The co-simulation method was used in the suspension design course. Functional Virtual Prototype (FVP) technology based on Multi-Body System dynamics theory and the corresponding software package ADAMS were used in establishing the vehicle system model. Computer Aided Control System Design (CACSD) technology and corresponding software package MATLAB were used in establishing the active suspension control strategy model. These two parts were combined and the co-simulation was made. It becomes a systematic method for vehicle-road interactive research and active suspension design. The resulting active suspension system can reduce the dynamic vehicle forces so that the strain fatigue life of road can be prolonged and the vehicle-generated road damage can be reduced.
