Design and analysis of regenerative shock absorber using ball screw mechanism for vehicle suspension

This paper presents the modeling and analysis of Regenerative Shock Absorber (RSA) using ball screw mechanism. The RSA design converts the reciprocating linear motion of vehicle suspension using ball screw. Bevel gear and one-way bearing convert bidirectional rotation to unidirectional rotation and the power will be simultaneously generated. The RSA ball screw was modeled and simulated to study the characteristics, performance, and power generated. The damping force provided by RSA was analyzed with various spur gear ratios to know the damping force value. The quarter car model was simulated to know the characteristic of a vehicle body when RSA is installed. The model is based on SUV with a spur gear ratio of 1.25. With various excitation frequency which proportional to vehicle speed, the RMS power generated was 21.7 W and maximum power 40 W at 60 km/h. The RMS vehicle body vertical acceleration is 1.71 m/s2 and reduce 8.6% than RSA hydraulic type in previous work.This paper presents the modeling and analysis of Regenerative Shock Absorber (RSA) using ball screw mechanism.
