摘要
针对某舵机用电机制动器组合在加速度环境下解锁呈现的离散性问题,通过机理分析、有限元仿真和试验验证,得出制动器不能可靠解锁的原因在于电磁力未能完全克服加速度环境下产生的负载增量.通过机壳、端盖一体化结构设计进一步提升制动器的有效电磁体积,通过增加安匝数和调整漆包线线径满足电磁力、阈值电流的要求,并设置常态环境下的强制检验点来确保制动器在加速度环境下能可靠解锁.
Abstract
Aiming at the discrete problem of the electric machine-brake complex of an actuator when unlocking under accel-eration environment,mechanism analysis,finite element simulation and test verification are carried out,and it is concluded that the reason of unreliable unlocking is that the electromagnetic force cannot completely overcome the load increment gen-erated under acceleration environment.Through the integrated structural design of the housing and the end cover,the effec-tive electromagnetic volume of the brake is improved,and the requirements for the electromagnetic force and threshold cur-rent are met by increasing the ampere-turns and adjusting the diameter of the enameled wires.The mandatory inspection point is set under normal environment to ensure that the brake can be unlocked reliably in the acceleration environment.
