Abstract :
This paper analyzed the structure and principle of a regenerative electromagnetic shock absorber in detail. The innovative shock absorber resembles linear generator in principle and can generate electric power through the relative reciprocating motion between coil assembly and permanent magnet assembly. At the same time, the damping can remove discomfort caused by road roughness. The regenerated electric power can be recovered through battery. The structure parameters of the shock absorber and performance parameters of shock absorber material were determined according to vehicle weighing 1.3 ton. The finite element analysis was carried to magnetic field of the shock absorber. The performance parameters of shock absorber were calculated according to structure parameters and magnetic field analysis result. Analysis and calculation results prove the viability of this shock absorber.
