摘要
对奥迪100型轿车悬架物理模型进行简化,建立奥迪100型轿车被动悬架数学模型——6个变量的一阶非线性微分方程组,应用Matlab2007/Simulink对其进行仿真计算,采用加速度均方根值分析评价汽车悬架在承受各种参数变化时的行驶平顺性。在此基础上,给出改变奥迪100型轿车悬架结构参数以提高其行驶平顺性的若干途径以及加速度均方根值与悬架刚度和簧载质量的拟合公式。
The physical model of the Audi 100 passive suspension system was simplified, and the mathematical models which were first order non-linear differential equations with six variables were developed. The ride comfort was simulated under the variations of several parameters with Matlab2007 / Simulink software to judge the ride comfort in terms of root mean square value of the accelera- tion. On the basis of those, the methods of improving ride quality of Audi 100 cars were presented, and fitting formulas between root mean square value of the acceleration and the suspension stiffness or mass were given.
