[Abstract]:With the development of micro-electromechanical technology, it has become a hot point in nonlinear dynamics research to use the environmental vibration to self-supply the system. The bistable electromagnetic vibration energy trapping device with linear oscillator is taken as the research object. The dynamic equations of the system are established, and the dynamic behavior of the bistable energy capture system under the excitation of colored noise is studied by numerical simulation. The dynamic response of bistable system is studied in three aspects: mass ratio and frequency modulation ratio. The influence of the above parameters on the dynamic characteristics of bistable energy capture system is obtained. These results provide a theoretical basis for the research of bistable electromagnetic vibration energy capture system.
