| Abstract: | This article has measured the stress of Axial Suspending Tube on SS 7C Locomotive According to the record,we have got the planar stress chart,estimated the fatigue life of the Axial Suspending Tube At the same time,we also estimated the crack growth life and the critical crack size of the Axial Suspending Tube These have provided the gist to confirm the rational overhaul period |
