Ride Vibration Simulation Test Based on Vehicle Model

Based on vehicle mode,vehicle vibration results are obtained from simulation test,vehicle ride by adjusting suspension stiffness coefficient and damping coefficient to reasonable values is improved.According to GB/T 5902-86(Method of pulse input running test-automobile ride comfort),vehicle vibration will be outputted after inputting simulated pulse to vehicle mode,then suspension stiffness coefficient and damping coefficient will be adjusted according to the condition of vehicle vibration.Real test data proved that the half car mode can respond the real vibration situation,so simulated pulse test based on half car mode can conduct suspension design in right direction.
