Modelling and Validation of Vehicle Ride Comfort Model

This paper presents the development of a validated seven degrees of freedom (7DOF) of vehicle ride comfort model for a Malaysian made passenger vehicle. The mathematical equations of the ride model, which consists seven degrees of freedom, are represented. Ride test known as pitch mode test was conducted to validate the reliability of the developed simulation model. The test was conducted using a fully instrumented test vehicle where the sensors installed were used to gather information on vehicle’s vertical and pitch motions. The data collected are used to tune certain parameters value in the simulation model, to ensure the developed simulation model can be used to represent the ride dynamics behaviour of the test vehicle. The result shows that the developed simulation model is capable in representing the ride dynamics behaviour of the test vehicle.
