The piezoelectric vibration energy collection technology utilizes the positive piezoelectric effect of the piezoelectric material, and collects the energy by attaching the material to a clamping structure and deforming under the external excitation, thus accumulating the charge and generating the potential difference. In this paper, the cantilever beam is used as a clamping structure because of its large deflection and simple structure. In this paper, the raindrop impulsion is applied to the piezoelectric material, the piezoelectric vibration energy capture device is used to improve the energy collection efficiency, and the electromechanical coupling model is established to simplify the potential energy analysis by using the conservation of energy and Newton’s second law. In this paper, Runge-kutta method is used to simulate the differential equation, which reduces the computational cost of the system and has a certain precision for analysis and solution. Based on Al-‘Ula’s Bernoulli beam theory, the model was simulated by using the differential equation method and the ordinary differential equation group.
