Aiming at the difficulties in the overall analysis of the failure of aircraft pipelines

a rapid method for analyzing the strength of aircraft pipelines is proposed. Combining CAEPIPE software with ABAQUS software

the finite element method is used to simulate the strength of the aircraft pipeline. For the analysis difficulties caused by the existence of flexible joints in aircraft piping systems

first

the CAEPIPE software is used to analyze the pipeline system as a whole

eliminating the complex iterative calculation for flexible joints in the traditional overall analysis. Then

based on the overall analysis

further detailed analysis of the dangerous area using ABAQUS software is carried out to ensure the accuracy of the intensity analysis. The proposed analysis method greatly improves the efficiency of the analysis based on the reliability of the strength analysis.The research work has reference value for clarifying changes in aircraft pipelines after loading

studying the failure mode of pipelines

checking pipelines strength

and optimizing the piping system structure.
