Problems solved by technology

The structure uses various electromechanical conversion methods to convert this kinetic energy into electrical energy, but the structure of the cantilever beam itself cannot have too much deformation, so the cantilever beam cannot have too small rigidity, and the quality of the mass block at the end should not be too high. Otherwise, the cantilever beam may break or deform. It is not difficult to see from the vibration system composed of spring and mass block that the efficiency of converting mechanical energy into electrical energy is low. Therefore, it can be seen that the vibration energy simulation device for low frequency It is not yet mature, so a new vibration energy simulation device that solves the above problems is needed in practice
