摘　　要：根据车辆参数进行悬架系统受力分析,得到螺旋弹簧所受压缩力;然后结合悬架系统关键参数计算公式和MATLAB/Guide模块,完成GUI界面创建和回调函数程序编写,运行得到刚度、阻尼系数和偏频等参数;最后借助Simulink建立1/2车辆五自由度动力学模型,从车辆垂直振动加速度、悬架动扰度和车轮动载荷3个方面对悬架系统进行仿真分析。引入MATLAB实现了多轴越野车悬架系统参数计算和仿真分析程序化、模块化,对提高设计效率和悬架系统性能分析具有重要意义。The compressive strength of the spiral spring was gotten through force analysis of the suspension system based on the parameters of the vehicle. The interface of the Guide was established and the callback function procedure was compiled combining with computational formula of the key parameter of the suspension system and MATLAB/Guide module,and the parameters of the stiffness,damping coefficient and deviation frequency were gotten. Then,the 5-DOF dynamical model of the 1/2 vehicle was established through Simulink,the simulation analysis was carried out on the suspension system from three aspects including the vertical vibration acceleration,suspension dynamic vehicle immunity and wheel dynamic load. The introduction of MATLAB achieved programmed and modularization for the parameter calculation and simulated analysis of the suspension system of multi-axle wheeled armored vehicle; meanwhile,it＇s of great significance on improving the design efficiency and performance analysis of the suspension system.
