The basic fatiguefailure characteristics have been analyzed according to the stress analysis and simulation test under inhomogeneous swallowtail between compressor disk and blade.
To establish and verify the failure mode, trouble reappearing and low -cycle fatigue tests are conducted on component test rigs.
为确定与验证锥齿轮故障模式,在试验器上进行故障再现试验及低周疲劳试验。

Some in-site vibrating test and metal fracture analysis have been done to reveal that the crack of the U-shaped bolts is fatiguefailure and some reference for designer is put forward.
