摘要
针对车辆的平顺性,选用四分之一车辆悬架作为研究对象,根据车辆悬架两自由度的运动微分方程,应用MATLAB/Simulink建立了车辆悬架的仿真模型。以某一车辆悬架参数为例,在正弦激励下得出轮胎加速度响应曲线和车身加速度响应曲线,并以加权加速度均方根值作为评价该车平顺性的指标,结果表明车辆在该种正弦激励下会使人感觉不舒适。
A quarter vehicle suspension was selected as the research object for vehicle ride comfort.According to the motion differential equation of two degrees of freedom of vehicle suspension,the simulation model of vehicle suspension was established by using MATLAB/Simulink.Based on the parameters of a car suspension,the corresponding curves of tire acceleration and car body acceleration were obtained under sine excitation.The weighted acceleration mean square root value was used as an index to evaluate the vehicle′s ride confort.
