| 摘 要： | 对某发动机经80h试车后四级压气机35~#转子叶片榫头折断故障做了分析。经金相与扫描电镜观察和模拟试验,使故障再现。分析认为,是加工配合过盈、局部接触应力过大出现微振磨损所致,并提出改进措施。

| Abstract: | Fracture of 4th rotor blade tenon No 35 of an aeroengine compressor has been analyzed using SEM and simulation test. The results shown that the blade is fatigue fracture caused by fretting between the tenon and tenon gear and the fretting is led by local large contact stress because of interference fit in machining. An improved measures has been proposed to prevent similar accidents. |
