ADAMS/Matlab 环境下车辆悬架联合仿真分析

摘要

Based on the one-fourth automotive dynamics model in ADAMS/View,the optimal co-simulation system is established in the environment of Matlab/Simulink through the data connection between ADAMS and Matlab, then, the comparison is represented in term of co-simulation and single simulation in Matlab. It shows both of these two approaches make acceleration value of suspension mass-loaded and consumptive energy reduce, however, the approach of co-simulation has more pronounced effect.%针对ADAMS/View环境下某车辆1/4整车动力学模型,通过ADAMS/Control模块建立了ADAMS与Matlab软件之间的通信连接,在Matlab/Simulink环境下建立最优联合控制系统,运用ADAMS和Matlab/Simulink软件(即ADAMS/Matlab)进行联合仿真,并与在Matlab单一环境下运行的仿真模型进行对比分析.结果发现:两种分析方法都能使车辆悬架簧上总质量质心加速度均方根值和控制能量降低,而ADAMS/Matlab软件联合仿真控制下的悬架簧上总质量质心加速度和控制能量下降幅度更大.
