【Abstract】 In this paper, a new devised automobile buffer is introduced. The buffer uses constrained magnetic field as its elastic media,its rigidity and the height of the automobile can be adjusted automatically. The structural and control design scheme and its operation mechanism of the buffer are presented. The vibration isolation capability of the magnet-suspended buffer is compared with liquid-air and coil ones, it is shown that the suggested buffer has good nonlinear elastic property and further improvement of the quality of ride will be obtained.更多还原
