摘　　要：在对JKM-1.6×4P型煤矿提升机及其天轮结构进行概述的基础上,利用ANSYS软件建立了天轮结构的仿真分析模型。结果发现,天轮结构虽然存在应力集中现象,但是最大应力远低于Q345-B材料的屈服强度,有必要对其开展轻量化设计。通过在轮辐区域设置8个扁椭圆形工艺孔的方式实现轻量化。选择4个关键结构及位置参数作为优化对象,以天轮质量作为优化目标,通过轻量化优化设计,使天轮整体质量降低了10.38%。将轻量化后的天轮部署到煤矿工程实践中,截至目前在煤矿中累计运行一年时间,发现整体运行安全且稳定。Based on the overview of JKM-1.6X4P coal mine hoist and its flywheel structure,the simulation and analysis model of the flywheel structure was established and calculated by using ANSYS software.It was found that although there is a stress concentration phenomenon in the sky wheel structure,the maximum stress is much lower than the yield strength of Q345-B material,and it is necessary to carry out lightweight design for it.Lightweighting is achieved by setting 8 flat elliptical process holes in the spoke area.Four key structural and positional parameters are selected as optimisation objects,and the mass of the flywheel is taken as the optimisation target.Through the lightweight optimisation design,the overall mass of the flywheel is reduced by 10.38%.The lightweighted flywheel has been deployed in coal mine engineering practice,and has been operated in the coal mine for one year,and the overall operation is found to be safe and stable.
