Abstract:

A complex car model was built for ride comfort analysis using ADAMS/Car and simulation of the model was performed on the random road and pulse road.A virtual simulation test rig was developed to test the car body natural frequencies.Comparison between test results and calculation results show the virtual simulation test rig is effective.The test rig provide a way for vehicle model body natural frequencies test. Using the methods of frequency domain analysis and time domain analysis, the full car transfer characteristic was researched. Based on these, the full car has been simplified to twofreedom model and vibration model was established using ADAMS/view. The factors of influencing vertical vibration have been researched, including suspension stiffness, damping , tire stiffness and so on. Influence of these factors on ride evaluation parameter was analysed.The analysis show that the variational rules of suspension working space, dynamic tire load along with the changing of suspension stiffness, damping.

Key words: vehicle engineering, automotive suspension, ride comfort, virtual simulation
