船用吊环优化设计研究

通过对吊环结构有限元强度分析，提出吊环优化设计方法，对4型吊环结构进行优化设计。在设计过程中，重点考虑吊环结构的强度优化设计、工艺的合理性、安全系数的统一和对横向受力角度进行量化的规定等，并采用拉伸试验对优化后的吊环结构强度进行试验论证，取得了良好的经济效益。同时又完成吊环标准的修订工作。

Study on the Design Optimization of Marine Lugs

This paper proposes a lug design optimization method based on finite element strength analysis and carries out design optimization for the structure of 4 types of lugs. The design process focuses on the optimization of lug structure strength, the technique rationality, the unification of safety factors and the quantitative regulation on transversal pull angle Then, the lug structure strength after optimization is experimentally verified based on tensile test, showing excellent social benefit. Meanwhile, the revision of lug standard is also completed.
