Technology Development of Cylindrical Fluid Resistance Shock Absorber for Motor Vehicle

The requirements of ride comfort, driving harshness and operating stability of a motor vehicle on character- istics of cylindrical fluid resistance shock absorber are analyzed, a motor vehicle has different requirements for shock absorber characteristics under different cases. The developing history of passive shock absorber and the features of air - charged and non air -charged shock absorbers are analyzed. The features working principle and their dynamic characteristics of me- chanical - controlled adjustable damping shock absorber, electronic - controlled shock absorber, changeable electric current and changeable magneic nuid liquid shock absorbers and etc. are explained. The defects of developing methods based on experience design/experimental modification of cylindrical shock absorber are analyzed, the processes and the critical problems in volved in modem design and developing method based on CAD/CAE technology are explained. Finally the de- veloping status and problems of cylindrical nuid resistance shock absorber technology in our country are analyzed and the developing trend of shock absorber technology is forecasted.
