摘要
为了让设计者从复杂的数学建模当中解放出来,从而专注于物理系统本身的研究,提出了一种可以基于AMESim与Simulink联合仿真的实验方法。以滤波白噪声作为路面输入,分别在AMESim和Simulink软件中搭建车辆1/4主动悬架模型,采用PID控制算法作为控制器,获得并分析了车身的垂直加速度、车身的动行程、车轮的动载荷的时域特性。仿真结果表明:由于两者的仿真曲线基本完全重合,所以采用何种搭建方法均可达到预期效果。同Simulink搭建的悬架模型相比,基于AMESim物理模型的建模方式更加图形化、简单化。
In order to free users from the tedious mathematical modeling and concentrate on the design of physical system itself.An experimental method based on AMESim and Simulink is proposed in this paper.The 1/4 active suspension model of vehicle is built in AMESim and Simulink software respectively with filtered white noise as road input.The time-domain characteristics of vertical acceleration,suspension dynamic deflection and tire dynamic load of vehicle body are obtained and analyzed by using PID control algorithm as controller.The simulation results show that the simulation curves of the two methods basically coincide,the expected results can be achieved by either method to build them.Compared with the suspension model built by Simulink,the modeling method based on AMESim physical model is more graphical and simplified.
