Experimental Study of Vehicle Modelling and Ride Comfort Simulation based on the Topology Structure Analysing

摘要

Topology was applied to analyse the structure of a certain domestic passenger car. All the subsystems were described with the topology graphics. And a dynamic model of the car was established by means of ADAMS, including front and rear suspension subsystem, steering subsystem, person-chair system, Fiala tire model and vehicle body. Combined with the Blevel road surface model, the simulation under random input was carried out. And the simulation results agree well with the experiment results. Through the comparison, the model proves to be reasonable and applicable.
