- 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.
