Research on the Fatigue Test Project of Axle Box Springs Used for CRH2 Multiple Units

NING Xiao-dan,SUN Bao-wei,SHANG Yue-jin,WANG Hong (Lanzhou Jiaotong University,Lanzhou 730070)  
Based on existed fatigue test specification of the cylindrical screw springs and the features of axle box Springs used for CRH2 Multiple Units,the fatigue test project is present by using the fatigue theory.In the complete quality of the spring surface and after the number of fatigue test reaches to 300 million,the springs can be judged when they are not broken.The research indicates that the plan can be used for inspecting product quality of axle box springs based on the fatigue test project.
