[Abstract]:As a vertical vehicle, elevators are indispensable in modern high-rise buildings.Elevator traction machine is an important part of elevator, its braking system is an important guarantee of elevator safe operation.The design and research of elevator traction braking system is of great significance to improve the safety of elevator system.This thesis is mainly about the design and research of permanent magnet synchronous gearless traction machine brake system.Firstly, according to the parameters of elevator system and the relevant requirements of Safety Code for Elevators and Escalators in American standard A17.1-2013, the minimum braking torque required for safe braking of elevator system is calculated and determined by combining force theory.It includes normal braking torque and emergency braking torque. Secondly, according to the calculation of braking torque, using ANSYS electromagnetic analysis and strength analysis software, the size of the electromagnetic force and the basic structure size of the brake are determined, and the dynamic, static disk strength and deformation of the brake are checked.Selecting the brake friction plate reasonably; then, aiming at some problems in the application of the brake, first of all, aiming at the brake noise, using the noise radiation theory numerical analysis, considering a variety of implementation schemes,It can effectively improve the suction and release noise of brake. Secondly, it simulates the heat of brake in the actual braking process, and uses ANSYS temperature field analysis to simulate the heating state of actual brake plate, which provides the theoretical basis for the temperature control of brake plate.Finally, the design of the above theory is tested and confirmed to verify that the performance of the brake meets the expected requirements well, and realizes the combination of theory and practice.In this paper, the design calculation and analysis are carried out in theory, and the design scheme is verified by test and test, which provides a theoretical basis for the system design of elevator tractor brake.
