微型汽车悬架的动态仿真方法

Study on Dynamic Simulation of The Minimotor’s Suspension

本文建立了微型汽车四自由度的动力学模型，推导出了计算公式，编制了悬挂系统特性仿真计算的程序。并以长安微车为实例对加速度、相对动载、动挠度功率谱和加速度均方根值进行了不同路面的模拟计算。该程序对汽车的设计和评价具有一定的作用。

The four DOF dynamic model of the minimotor is established in the paper. Author derives the formula and the computer programs are developed according to the model. Power spectrums of acceleration, relative dynamic load and dynamic deflection are simulated to the Changan minimotor on different roads. So does acceleration's mean square root value. The program is of practical value to design and evaluation of minimotors.
