Check and Analysis on Traction Spindle of High-Speed Elevator Based on ABAQUS Simulation
The main shaft is an important part of high-speed traction elevator,which must bear the impact of different torques and varying loads in elevator operation.In the design of the main shaft of the traction machine,the finite element analysis of the main shaft is carried out by using ABAQUS software.Firstly,the three-dimen-sional model of the main shaft is constructed,and two working conditions are simplified according to the environ-mental variables of the actual work of the main shaft:smooth operation of the main shaft without eccentric force and the presence of eccentric force.Secondly,the spindle is checked and modal analysis is carried out to deter-mine the natural frequencies of the spindle system and modal modes,and each order modal mode can be accu-rately obtained.The simulation results show that the spindle design is effective.Finally,through the installation and debugging of the elevator spindle in the field,the results of finite element simulation analysis are verified.The test proves that it is reasonable and feasible to use ABAUQS software to check and analyze the elevator trac-tor spindle.This method is suitable for the design and check of other shaft parts.
