Abstract
Provided is a damper for a semi-active energy regenerative suspension based on hybrid excitation. The damper includes: an upper lifting lug, a dustcover, a lower lifting lug, a hydraulic shock absorber, and a hybrid excitation mechanism, wherein the hydraulic shock absorber is configured to provide a constant viscous damping coefficient, and wherein the hybrid excitation mechanism is configured to generate an adjustable electromagnetic damping force, to transform the vibration energy into electrical energy, and to storage the electrical energy. Also provided is a method for determining the sizes of the damper. The damper which has a simple structure, balances the vibration isolation property and energy regenerative property of the vehicle suspension, and provides a fail-safe function. Furthermore, the method for determining the sizes of the damper is easy and practical to implement, has definite steps and produces drastically optimized results.
