摘要
建立了微型振动式发电机的核心部件振子的结构模型。利用有限元的方法对振子进行了动力学分析及计算 ,并应用ANSYS有限元分析软件 ,对振子进行了计算机模拟分析 ,得出了敏感元的厚度、宽度对振子固有频率及最大变形量的影响。设计出了优化的振子系统结构。
A structural model has been established for the spring-mass system and the key c omp onents of a micro vibration power generator. In order to calculate t he d eflection of the spring-mass system, dynamics finite element analysis (FEA) with the ANSYS Finite-Element program was performed, and the results der ived from FEA are analyzed for the structure and its displacement, resonant frequency and mode, and consequently, the whole st ructural design of the micro vibration power generator was optimized.
