A Full-Suspension Three-Wheeled ATV System: Part II - Roll, Pitch and Vertical Motions 860228

This paper is the second in a series on three-wheeled all-terrain vehicle with full suspension. It investigates and compares the roll, pitch and vertical motions of a thirteen degrees-of-freedom mathematical model of a vehicle/rider system with full mechanical suspensions and a six degrees-of-freedom system with no mechanical suspensions. The three different bump profiles - rectangular, parabolic and sinusoidal - employed in the excitation of the system in Ref. (1)* were used for this system. The results show that the current system has substantially reduced roll, pitch and vertical displacements. As a result, it is better in ride and handling as compared to the previously simulated system (1).
