Abstract :
Modal analysis is a technology for vibration characteristic research. It is the foundation for structural dynamics analysis. Natural frequency is a very important performance in dynamics analysis. Modal characteristics of the Permanent Magnet Linear Synchronous Motor (PMLSM) for ropeless elevator were investigated by finite element method (FEM). FEM models for modal analysis were built for the primary winding, iron core, fixed block, secondary back iron and permanent block by appropriate structure simplification. The influences on natural frequencies of the PMLSM were analyzed. Natural frequencies and mode shapes were simulated by FEM. The accuracy of the FEM analysis is validated by the modal analysis experiment of hammering method.
