摘要
建立了汽车油气悬挂系统非线性数学模型和1/4车数学模型,应用Matlab软件编制了计算机仿真程序,利用仿真程序得到了悬挂系统受力,悬挂质量、非悬挂质量和座椅的振动加速度,车轮动载、悬挂动行程等参数,为对汽车机平顺性、行驶安全性进行评价奠定了基础.
A nonlinear mathematical model of hydro-pneumatic suspension in vehicle and a quarter vehicle mathematical model are set up. Computer programs for simulation using Matlab/simulink is developed. By using the computer simulation program, we can obtain the parameters which include the acceleration of the unsprung mass , the sprung mass and the chair, dynamic force of the tyre and dynamic displacement of the suspension, which provides the basis for evaluating the vehicle's riding comfort and riding safety.
