基于故障树分析的发动机高压转子抱轴故障诊断
Fault diagnosis of engine high-pressure rotor seizure based on fault tree analysis
摘要
Abstract
To address the issue of high-pressure rotor seizure after engine shutdown,a fault tree analysis method based on Isograph was employed to identify the causes of the high-pressure rotor seizure.By analyzing physical re-inspection results and performing deformation compatibility calculations for typical seal clearance locations,the root cause of the seizure was determined.Corresponding corrective measures were formulated and verified through engine testing,thereby further enhancing the efficiency of the overall engine test process.This approach can provide ideas and methods for addressing other rotor seizure issues,enabling targeted preventive measures to be taken in the early design stage and refining deformation compatibility theory from an engineering application perspective.关键词
