PROJECT TITLE :

Regenerative Shock Absorber Using a Two-Leg Motion Conversion Mechanism

ABSTRACT:

This paper presents the event of a completely unique regenerative shock absorber sized for a passenger car suspension system. The shock absorber includes a simple and highly efficient motion converter called a two-leg mechanism , a planetary gearhead, and a brushless 3-section rotary machine. The look and analysis of the regenerative shock absorber are presented by considering the dynamics and efficiency of the electromechanical device. The performance of the regenerative damper is evaluated beneath sinusoidal excitation inputs for typical amplitudes and frequencies during a vehicular suspension system. Experimental results show that a damping coefficient of $1720$ N$cdot$s/m will be achieved by controlling the external loads. Furthermore, a mechanical energy conversion potency between zero.71 and 0.eighty four is achieved, which is considerably higher than alternative mechanisms reported in the literature, like ball screw, rack-and-pinion, and linear mechanisms.
