摘　　要：针对现役单绳缠绕式矿井提升机主轴装置的人孔周边、主轴和卷筒上不时有裂纹产生的问题,提出了综合利用Pro/E、HyperMesh、ANSYS等软件来构建其三维实体模型、分析其应力应变场,将OptiStruct软件用于主轴装置人孔结构的优化设计中,以解决其薄弱环节问题,确保其在正常工况下安全运行的现代设计方法。研究结果表明:计算结果与主轴装置常见故障基本一致;人孔周边应力减小约26.7%。该研究成果已被企业设计部门成功应用于JK型提升机主轴装置的人孔结构和主轴轴承台阶处的设计,在实际运行过程中取得了较为满意的效果。Aiming at some cracks that were appeared on the drum shell, mare snaft and around manholes in the main shaft device of a mine hoist with single--winding wire rope at times, a modern design method was put forward herein, where the softwares of Pro/ENGINEER, HyperMesh and ANSYS were comprehensively used to construct the three dimensional solid model, and to simulate and analyze the stress and strain fields of the main shaft device numerically,and the software of OptiStruct was creatively applied to optimize the manhole structure of the main shaft device in order to resolve the weakness in structure and to ensure its safe operation in normal working condition, The research results show that： the computational results basically consist with the common failure in the shaft device,the stress around manholes is reduced by about 26.7%. The research result has been ap-plied to design the manhole and sidestep structure of the main shaft device in JK--hoist by the corporate design department, and the effect in the practical operation is satisfactory.
