摘　　要：针对永磁外转子提升机卷筒运行时非线性、强耦合等复杂受力问题,以矿用缠绕式永磁外转子提升机为研究对象,进行了卷筒动态受载变形及优化的研究。首先利用SimulationX软件搭建了永磁外转子提升机电控-机械联合仿真模型,准确获取了重载上提工况下钢丝绳动态张力及电磁转矩,再通过有限元数值模拟得到外转子卷筒应力及变形规律,最后,采用隔离环或加强筋将钢丝绳缠绕卷筒与转子轭分离,完成其结构优化。研究表明:重载上提工况下外转子卷筒最大等效应力与径向变形呈非线性增加,整个运行阶段,最大应力及变形基本稳定在固定区域,采用分离处理的优化方式有效降低了定转子间气隙变形。Aiming at the complex stress problems such as nonlinear and strong coupling when the drum of the permanent magnet outer rotor hoist is running,the dynamic load deformation and optimization of the drum of the mine winding permanent magnet outer rotor hoist are studied.Firstly,the electric control-mechanical joint simulation model of permanent magnet outer rotor hoist is built by SimulationX software,and the dynamic tension and electromagnetic torque of steel wire rope under heavy load lifting condition are accurately obtained.Then,the stress and deformation law of outer rotor drum are obtained by finite element numerical simulation.Finally,the steel wire rope winding drum is separated from the rotor yoke by isolation ring or reinforcing rib,and its structure is optimized.The research shows that the maximum equivalent stress and radial deformation of the outer rotor drum increase nonlinearly in heavy load lifting,and the maximum stress and deformation are basically stable in the fixed area during the whole operation stage.The optimization method of separation treatment is adopted to reduce the air gap deformation between stator and rotor.
