【摘要】：电梯作为垂直方向的交通工具,在现代高层建筑中不可或缺。电梯曳引机是电梯的重要组成部分,其制动系统是电梯安全运行的重要保障。电梯曳引机制动系统的设计与研究,对提高电梯系统的安全,意义深远。本课题主要是对永磁同步无齿轮曳引机制动器系统的设计与研究。首先,依据电梯系统参数及美国标准A17.1-2013《Safety Code for Elevators and Escalators》中关于制动的相关要求,结合力学理论,计算并确定电梯系统安全制动所需要的最小制动力矩,包括正常制动力矩和紧急制动力矩；其次,根据计算制动力矩,采用ANSYS电磁分析及强度分析软件,确定制动器电磁力大小及基本结构尺寸,校核制动器动、静盘强度及变形,合理选择制动器摩擦片；然后,针对制动器在应用的一些问题进行分析,首先针对制动噪音,采用噪声辐射理论数值分析,考虑多种实施方案,有效改善制动器吸合及释放噪音；其次模拟制动器在实际制动过程的发热,采用ANSYS温度场分析模拟实际闸片的发热状况,为闸片的温度控制提供理论依据,有效提高制动器的安全寿命；最后,对上述理论设计,进行试验测试确认,验证制动器的各项性能很好的达到了预期要求,实现了理论与实际的结合。本课题研究内容,先从理论上进行设计计算及分析,并通过试验测试确认,验证设计方案,为电梯曳引机制动器的系统设计提供了理论依据。
[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.
