摘要
通过对飞机平尾大轴疲劳试验过程中声发射信号的分析,发现了异常的声发射集中部位,综合分析认为这是由于异常摩擦机制造成的声发射,分析结果得到了卸载目视检查结果的验证。
Through study, ing acoustic emission signal on flight stabilizer spindle of fatigue tests,discovered the unconventionality acoustic emission signal and located the location of it. Found out the reason is exceptional friction. The result has been validated by eyes after unloading the force.
