    Abstract
  • Low cycle fatigue test, high cycle fatigue test under rotating bending and crack growth rate test of EA4 T alloy steel were carried out. Considering load type, surface quality, dimension coefficient and other factors, the fatigue limit of standard small specimen was modified to predict the fatigue performance of full-scale axle. The finite element model of railway axle with inside axle box (RAIB) was established. The difference of critical safety position between RAIB and traditional railway axle with outside axle box (RAOB) was analyzed. Based on the safe life design theory, combined with the modified linear Miner fatigue cumulative damage criterion and load spectrum, the fatigue strength and service performance of RAIB were studied. The crack growth rate curves were fitted by using the Paris formula, NASGRO equation and LAPS model, respectively. Based on the damage tolerance design method, the crack propagation lifes of RAIB and RAOB were estimated. Analysis result shows that the fatigue limits of standard small specimens is obviously higher than that of full-scale axles, and the mean values of fatigue limit are 369 and 286 MPa, respectively. Compared with the traditional RAOB, the critical safety position of RAIB has been transferred from unload groove to axle center due to the change of loading position. The total fatigue life of RAIB is 2.5×1012 km, which meets the design requirements of 30-year service life. However, there are inevitably defects on the surface of the axle during transportation or service, and serious stress concentration exists at the defect, which provides convenient conditions for the initiation and propagation of cracks and greatly reduces the fatigue life of axle. When the crack depth in critical safety position of axle extends to 5 mm, the residual lives of RAIB and RAOB are only 3.2×105 and 2.0×105 km, respectively, and the non-destructive inspection interval should be reasonably formulated according to the accuracy of non-destructive test to ensure the safe service of axle.
