摘要
为研究轮毂电机对车辆平顺性的影响,文章建立了1/4车辆二自由度振动系统模型和随机路面输入模型,以MATLAB/Simulink为仿真平台建立了相应仿真模型,通过仿真得到了不同非簧载质量情况下车身加速度、车轮相对动载荷以及悬架动挠度对路面速度激励的响应。最后,分别从频域和时域角度对振动系统响应进行分析,结果表明,随着非簧载质量的增加,车辆的平顺性变差。
In order to study the influence of hub motor on vehicle ride comfort,the 1/4 vehicle two degree of freedom vibration system model and random road input model are established.Taking MATLAB/Simulink as the simulation platform,the corresponding simulation model is established.Through the simulation,the responses of vehicle body acceleration,wheel relative dynamic load and suspension dynamic deflection to road speed excitation under different unsprung masses are obtained.Finally,the response of the vibration system is analyzed from frequency domain and time domain respectively.The results show that the vehicle ride comfort becomes worse with the increase of unsprung mass.
