Analysis and Improvement on Vertical Vibration of Elevator with Permanent-magnet Synchronous Traction Drive

The paper presents an analytical study on permanent-magnet synchronous traction drive elevator and builds dynamic modeling equations. In this study, it is proposed that a new means of distributing system stiffness coefficients and a simultaneous means of disturbance. MATLAB software is applied for numerical analysis on every part of elevator and resolves simultaneous vibration. Based on the equations above, elevator system stiffness is improved. Both before and after improvement vibration data are computationally and experimentally obtained and are in good agreement. It achieves the goal of improving elevator vibration. The results of study can be used to predict operating performance of elevator with different system stiffness. It is useful in studies related to performance improvement, optimization and treatment with high-speed elevator＇s vibration and noise.
