Modal analysis and linear static structure analysis of linear switched reluctance motor

In order to study the mechanical characteristics of the linear switched reluctance motors (LSRMs), modal analysis and linear static structure analysis of a LSRM is investigated in this paper. Basic theories of modal analysis and linear static structure analysis are stated. The structure of the LSRM is illustrated. And the modal analysis and linear static structure analysis by finite element method are demonstrated based on ANSYS workbench. The first six natural frequencies with the corresponding mode shapes and the deformation of the LSRM are obtained. The results show that the first six natural frequencies of the LSRM range from 2244.7 Hz to 4033.1 Hz, the deformation of the LSRM is within 0.0020546 mm under the largest normal force, and the easiest deformation part of the LSRM is the mover platform. The results verify that the mechanical design of the LSRM is reasonable.
