Abstract: The present invention discloses an asymmetrical PN junction thermoelectric couple structure and its parameter determination method. By changing the structural parameters of p-type semiconductor or n-type semiconductor, the current generated by p-type semiconductor is equal to the current generated by the n-type semiconductor, so that the high-efficiency output of PN junction thermoelectric couple can be realized. Meanwhile, the present invention provides a method for determining the parameters of PN junction based on the numerical solution method. Finally, the optimal size parameters of PN junction are obtained.

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.
