Experimental Study on Fatigue Properties of Titanium-steel Cladding Welded Transition Joint for Warship

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.
