| 摘 要： | 针对舰船用钛-钢复合过渡接头应用要求,进行了钛-钢过渡接头焊接态拉-压、拉-剪和弯曲疲劳试验,结果表明,疲劳寿命为200万次时,钛钢复合过渡接头结构件的拉-压疲劳极限为73.0 MPa,拉-剪疲劳极限为62.96 MPa,弯曲疲劳最大应力达到360 MPa且接头本身未破坏。拉-压疲劳和拉-剪疲劳S-N曲线可为舰船钛-钢复合过渡接头结构的设计提供支撑。

| Abstract: | In accordance with requirements of engineering applications,experimental studies on tension-compression,tensionshear and bend fatigue properties of titanium-steel cladding welded transition joint were conducted.The results showed that when the fatigue life was 2 × 106 cycles,the tension-compression and tension-shear fatigue limits of the welded transition joint were 73.0 and 62.96 MPa,respectively,and the bending fatigue stress of the clad plate was 360 MPa,with the joint in good condition.The tension-compression and tension-shear S-N fatigue curves could provide technical support for the design of titaniumsteel cladding transition joint for warship. |
