Abstract：The circular composite piezoelectric structure can convert mechanical energy into electrical energy,so as to supply energy for the intelligent sensing sensors of the running parts of rail vehicles.In this paper,the frequency response characteristics of circular plate composite piezoelectric structures are studied.Based on the COMSOL finite element software and ISIGHT optimization design platform,a simulation model of circular plate composite piezoelectric structures is constructed.The key factors affecting the frequency response characteristics of piezoelectric structures are obtained through DOE orthogonal tests.Based on the analysis re-sults,single parameter analysis and correlation analysis are carried out.Among them,the diameter of the metal substrate and the height of the mass block have a negative effect on the first three modal frequencies of the structure,and the diameter and thickness of the piezoelectric ceramics have a positive effect on the first three modal frequencies of the structure,which lays a certain founda-tion for the subsequent structural optimization design.
