摘要：

Taking the central frame of the electric wheelchair as the research object, the finite element analysis software MSC.Patran /Nastran is used to model the finite element and the modal analysis in the undamped state, and the first 10 modes of the central frame structure are obtained. By analyzing the simulation results of the modal, the natural frequencies of the 1st to 10th order of the central frame structure and the 1st to 10th order modes corresponding to the frequency are effectively designed to avoid the resonance phenomenon of the electric wheelchair stem.And it verifies that the central frame structure satisfies the requirements of dynamic characteristics, conforms to the safety and rationality of the structural design, and provides a reference for the further optimization and design of the structure.
