Self-powered Active Suspension for Vehicle

In this paper,a new active suspen- sion is proposed,which is called self-powered ac- tive suspension (SPAS).The feature of the new suspension is that when vibration of system is re- duced,the vibration energy can be converted into electrical power and be stored in the capacitor,the active force can be generated from the electrical en- ergy to control the motion of systems.Such sys- tems don't require external energy.For a 2-DOF singlewheel system,the configuration and principle of the SPAS are introduced,and the conditions in- suring the energy balance are analyzed.The sys- tems'performances are simulated.
