摘要
对SS7C电力机车抱轴承箱进行动应力实测 ,根据动应力实测编制了抱轴箱的二维应力谱 ,对抱轴箱的疲劳寿命进行了估算 ,同时也估算了抱轴箱体的裂纹扩展寿命和临界裂纹尺寸 ,为确定合理的检修周期提供依据。
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
