Description

Technical field:

[0001] The invention relates to a dual-rotor self-powered shock absorber based on a magneto-rheological elastomer. Background technique:

[0002] The shock absorber (Vibration Damper) is mainly used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road surface. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road surface, the spring itself will reciprocate, and the shock absorber is used to suppress this spring jumping. Shock absorber is too soft, automobile body can hop up and down, shock absorber can bring too great resistance too forcedly, cloggy bedspring works normally.

[0003] For a general shock absorber, its damping is fixed, which also determines that the designer can only choose one between comfort and sportiness, or choose a soft and hard shock absorber that is a compromise. To make a model both comfortable and sporty, the shock absorbers must...
