摘要:
为研究非平稳路面激励下车辆振动特性,建立了非平稳路面时域模型及1/2车身的五自由度汽车振动模型.运用M argenau-Hill时频分析方法,对非平稳路面汽车前后轮激励进行时频特性分析,结果表明非平稳路面激励具有低频波动特性.最后以第二类拉格朗日法为理论基础,建立振动动力学方程,并借助MATLAB/simulink建立振动仿真模型,得出在非平稳路面激励下,分别适当减小汽车座椅悬架与后悬架刚度以及提高汽车座椅悬架与后悬架阻尼,可以提高驾驶员的乘坐舒适性.
Abstract:
In order to research the light agricultural vehicle ride under the stimulation of the road, We estab-lished a non-stationary road excitation model and half of the vehicle which have 5-DOF vibration model. TheMargenau-Hill time-frequency analysis tools was used to study the non-stationary excitation of the vehicles ofthe front and rear wheels roughness. and the results showed that non-stationary road stimulation have low-frequency and wave characteristics. Finally, based on the method of Lagrange, we established a dynamics equa-tion modeling of vibration, using matlab/simulink and set up 5-DOF vibration simulation model and obtain aresult, under the excitation of the road, to reduce the seat and rear suspension stiffness and to increase theseat and rear suspension damper can improve the driver’s sense of comfort.
