非平稳路面激励下车辆振动动力学建模与仿真
Modeling and Dynamic Simulation of Vehicles Based on Non-stationary Road Excitation
摘要
Abstract
In order to research the light agricultural vehicle ride under the stimulation of the road, We established a non-stationary road excitation model and half of the vehicle which have 5-DOF vibration model. The Margenau-Hill time-frequency analysis tools was used to study the non-stationary excitation of the vehicles of the 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 equation modeling of vibration, using matlab/simulink and set up 5-DOF vibration simulation model and obtain a result, under the excitation of the road, to reduce the seat and rear suspension stiffness and to increase the seat and rear suspension damper can improve the driver' s sense of comfort.关键词
