摘　　要：文章以智能研究与实训两用船项目为依托,在不增加材料成本基础上提高T型吊耳使用次数,此次对现有T型吊耳进行优化设计,首次使用了有限元分析软件中弹塑性计算理论及规范公式进行吊耳自身结构、吊耳与被吊物之间焊缝的强度校核,达到T型吊耳强度满足2.5倍安全系数使用要求。结果显示该研究成果可为单船工装成本的压降提供一定作用。Based on the intelligent research and training ship project,the company increased the use times of the T-type lifting eye without increasing the material cost.This paper optimized the design of the existing lifting eye and first used the elastoplastic calculation theory and normal formula in the finite element analysis software to check the strength of the lifting eye's structure and the weld between the lifting eye and the lifted object,and the strength of the T-type lifting eye meet the requirements for 2.5 times of safety factor.The result shows that the research achieve-ment may play a role in reducing the cost of tooling on a single ship.
