Vibration Test of Titanium Alloy Pipes

摘要：

　　In order to determine the fatigue limits of two kinds of titanium alloy pipes connected by welding and rolling,fatigue tests were carried out by the Aero-Criterion1 which gives vibration fatigue test method and failure criteria.A laser-displacement-sensor was used at the free end and a strain-gauge at the root of the pipe specimen.The test result shows that the fatigue limit of the welded pipe is higher than the rolled one.In the end some new findings are listed according to the test.
