- Abstract
A front wheel suspension system of a motorcycle is assigned to a quarter car model and from which one shock
absorber is considered for the performance study. The deviations from the cycloidal rotation of the wheel are proposed
and the vertical motion of the wheel with respect to the sinusoidal road surface is modelled by a polynomial equation
and compared with the experimental data. To give deterministic impulses due to road profile, the adjustable bumps are
angularly mounted on a variable eccentric cam which gives input motion to a shock absorber mounted upright above it
and acting as follower to the cam. For the heavier loads the rebound of shock absorber reduces and displacement
smoothens. There occurs a combination of speed range, load and road disturbances within which the vertical
acceleration is within the standard limit.
