Abstract
The plane vibration model of minibus with seven degree-of-freedom and its vibration response variables are established according to the plane and linear assumptions. The road pulse input is expressed based on Chinese standard with number of GB/T4970-2009. Ride comfort simulation software of minibus under road pulse input is developed with Matlab and applied to ride comfort analysis of minibus under road pulse input. A minibus is selected to analyze its ride comfort and the maximum absolute value of the vibration response variables are obtained at the speed from 10 to 60 kmh-1. The results show that the model and software can be used to ride comfort simulation of a minibus under road pulse input.
