摘　　要：针对绞缆机卷筒理论承载能力远大于实际所承受负载造成自重过大的问题,文章通过Ansys Workbench对卷筒进行静力学分析,得出支持负载下卷筒最大应力远小于许用应力值,在此基础上对卷筒进行结构优化和强度校核,同时对比传统的稳定性计算方法和有限元计算方法。结果表明,结构优化后轻量化效果明显,卷筒临界载荷为1175.2 MPa,卷筒稳定性满足要求。The theoretical bearing capacity of a mooring winch drum is much larger than the actual load.In view of this problem,this paper conducts a static analysis of the drum by Ansys Workbench,and it is concluded that the maximum stress of the drum under the supporting load is far less than the allowable stress.On this basis,the structure optimization and strength check of the drum are carried out,and the traditional stability calculation method and the finite element calculation method are compared.The results show that upon the structure optimization,the lightweight effects are significant,and the critical load of the drum is 1,175.2 MPa.Thus,the stability of the drum meets the requirements.
