雷体

The fem analysis for the three structures of sling screw - thread - based , namely the circle , rectangle and that with strengthen plate , and the tensile test for sling screw - thread - based in torpedo body show , that the bonding with strengthen frp plate between load - bearing metal parts and frp hull with hatch can reduce the stress concentration and significantly decline the local stress in frp hull with hatch . this structure can also be used in the similar produces . ( 3 ) the effects of parameters for bonding process on the adhesive strength and leakproof are discussed , such as the bonding interface reduce , bonding surface treatment , match of adhesive surface , protect for adhesive seam and so on
本文通过某型号雷体吊耳螺纹座结构的三种方案，即圆形昂耳螺纹座、长方形吊耳螺纹座、具有增强板的吊耳螺纹座的有限元分析及雷体吊耳螺纹座拉力试验结果证明：金属承力件与开口玻璃钢壳体粘接采用玻璃钢增强板补强，缓和了应力集中，使开口壳体局部应力明显降低，类似的水下兵器用金属承力件与开口复合材料壳体胶接均可采用此种结构形式。
