The vibration energy collector of the dual-crystal piezoelectric beam structure can convert the mechanical vibration energy obtained by the running part of the vehicle into electric energy and supply power for rail transit vehicles’ small safety detection equipment. In order to solve this problem, firstly, the energy conversion model of the piezoelectric beam is used as the objective function, and the aspect ratio, Young’s modulus ratio, and thickness ratio of the beam are used as parameters. The design space is quantified concerning actual application conditions. The seagull algorithm is used to propose an optimized design for the dual-crystal rectangular piezoelectric beam fixed at both ends of the PZT-5H material commonly used in engineering. Solve it using an optimization algorithm. Finally, a test system was built for experimental verification, which provided a technical guarantee for the power supply of train sensors.
