Dynamic Analysis of Scooter (Two Wheeler) for Ride Evaluation 911875

Computer Simulation of ride dynamics of a two-wheeled scooter is carried out to seek directions of improvement in design of its suspension.
The paper deals with the study of a scooter adopting link type suspension both in front and rear. A five degree freedom planar model for a two wheeler is developed. It includes geometric nonlinearities due to linkage assembly in front and rear suspension, multi rate springs, shock absorber nonlinearity, suspension bottoming and wheel lift off. A good correlation was observed between the simulated and experimental results. It is shown here how adjustment in damping coefficients of the shock absorber improves the passenger comfort while passing over a road bump.
