摘要

建立了万向联轴器叉头的型线优化模型，基于分治法提出了一种针对叉头型线的优化策略，总结了6个设计变量对叉头最大应力的影响规律。研究表明，叉头圆弧槽和肩台的结构参数变化对叉头最大应力的影响显著，在设计时应当重点关注。开展了叉头型线优化的案例分析，在保持回转直径不变的前提下，有效降低了叉头的最大应力，提高了传扭能力。研制了目前国内船用传扭能力最大的某型重载万向联轴器，并开展了性能试验，为重载万向联轴器叉头的型线设计和优化提供了参考。

Abstract

A profile optimization model of the fork head of universal coupling is established. Based on divide and conquer, an optimization strategy for the profile of fork head is proposed. The influence law of the six design variables on the maximum stress of the fork head is summarized. Research shows that the structural parameters of arc groove and shoulder have a significant effect on the maximum stress of fork head, which should be paid attention to in design. According to the case analysis of fork profile optimization, on the premise of keeping the rotary diameter unchanged, the maximum stress of the fork head can be reduced and the torsion transfer ability can be increased. A heavy-duty universal coupling with the largest torsion transfer capacity in China is manufactured, and the performance test is carried out, which provides a reference for the design and optimization of fork head’s profile of heavy-duty universal coupling.
