摘要
针对飞机管路失效问题整体分析中存在的困难,提出了一种飞机管路强度快速分析方法,采用CAEPIPE软件与ABAQUS软件相结合的有限元方法对飞机管路的强度进行模拟分析。对于飞机管路系统中因柔性接头存在而引起的分析困难问题,首先利用CAEPIPE软件对管路系统进行整体分析,避免了传统分析方法中对于柔性接头的复杂迭代计算;在整体分析的基础上,针对危险区域利用ABAQUS软件进行进一步的局部分析,以保证强度分析的准确性。所提出的分析方法在保证强度分析可靠性的基础上,相对于传统分析方法大幅度提高了分析效率。研究工作对明确飞机管路受载后的变化情况、研究管路失效形式、校核管路强度、优化管路系统结构具有参考价值。
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.
