Abstract: Magneto-rheological shock absorber is a new type of shock absorber with continuously variable damping force, rapid response, simple mechanical device and small external input energy. In recent years, non-renewable energy sources have been increasingly depleted and carbon emissions have been too high. Based on the principle of sustainable development, new energy vehicles and electric vehicles will become an inevitable choice for the development of automobiles. Electronic and intelligent magnetorheological the shock absorber will surely achieve great development and application. The article first introduces the core technology of magnetorheological dampers, studies the settlement stability of magnetorheological materials and the solution to the energy problem of magnetorheological dampers, and then discusses the future development of magnetorheological dampers. Finally, the current research on magnetorheological dampers is summarized.

Key words: Magneto-rheological shock absorber; Controllable characteristics; Temperature rise characteristics; Semi-active suspension
