Abstract：In order to realize self-driven power supply of railway vehicle detection and sensing equipment,the power genera-tion characteristics of L-shaped piezoelectric energy harvester are modeled and studied,and the power generation model of piezo-electric energy harvester is established by force analysis of its installation position.COMSOL finite element software is used to com-pare the theoretical model.The relative errors of the first six orders of output power are all less than 3%,which verifies the correct-ness of the power generation model.
