主要对航空发动机摇臂裂纹故障进行统计、分析,并研究摇臂裂纹的修复技术。采用对零件原结构和修复后结构进行静强度计算的方法,确定裂纹修复标准;通过装机考核的方式,最终确定修复技术的可靠性。
Mainly on aeroengine rocker crack fault statistics, analysis, and research rocker arm crack repair technology. The original structure of the part and the static strength of the repaired structure are calculated to determine the standard of the crack repair. The reliability of the repairing technique is finally determined by the method of installed capacity assessment.
