摘要
拉环是连接水下拖曳体的一个关键承力构件,但是在实际使用过程中拉环焊缝出现了疲劳断裂。文章对拉环焊缝断裂原因进行了分析,通过改变拉环结构型式和焊接工艺两种方法进行改进,改进后拉环使用情况良好。
Pull ring is a key bearing component that connects the underwater towed body, but in actual use, fatigue fracture occurs in the pull ring weld. This paper analyses the reasons of the weld fracture of pull ring, and things are in good condition after being improved through two ways including the change of the structure of pull ring as well as welding.
