The effect of inclination angle of shock absorber on ride comfort and road holding of two-wheeled vehicle

Abstract

The main purpose of shock absorber assembled in a vehicle is for ride comfort of passengers and better control of moving vehicle by driver. The shock absorber is assembled in between vehicle body known as sprung mass and a combine mass of wheel and suspension known as unsprung mass. In the present work, the effect of inclination angle of shock absorber on ride comfort and road holding of two-wheeled vehicle has been analyzed. For this study, a commercial viscous damper of a two-wheeled vehicle is characterized for different frequency and sinusoidal stroke to find the damper characteristics. A linear curve is fitted for the maximum velocity versus damping force for rebound and compression region. The fitted curve and a bump road profile used to analyze the ride comfort and road holding of the two-wheeled vehicle for three different inclination angles made by shock absorber. The stiffness of suspension increases due to the inclination which influences the ride comfort and road holding. © 2020 Author(s).
