Abstract

Axle is an important component related to the safety of high-speed train operation. Axle failure will cause a series of safety problems. Therefore, in order to ensure that the axle will not fail during operation, it is necessary to establish a reasonable inspection interval to ensure that cracks can be detected in time before the axle breaks, so as to avoid the occurrence of axle failure events. In this paper, the axle inspection interval is calculated by the axle damage tolerance design method and the remaining life curve of the axle obtained by the full-scale axle crack propagation test. The evaluation of the remaining fatigue life of the axle is closer to the reality, which has certain design guiding significance and engineering application value.
