摘要
圆板式复合压电结构可将机械能转化为电能,从而为轨道车辆走行部件智能感知传感器供给能源。论文针对圆板式复合压电结构的频响特性进行研究,基于COMSOL有限元软件和ISIGHT优化设计平台进行联合仿真,构建了圆板式复合压电结构的仿真模型,通过DOE正交试验得到了影响压电结构频响特性的关键因素,并以此进行了单参数分析和相关性分析。其中,金属基板的直径和质量块高度对结构的前三阶模态频率呈负效应,压电陶瓷的直径和金属基板的厚度对结构的前三阶模态频率呈正效应,可为后续结构优化设计提供理论依据。
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 results,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 foundation for the subsequent structural optimization design.
