Open publisher page 0 citations

Abstract

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.
