摘要
对主起落架试验所用的加载框架采用有限元和传统强度计算方法,分别对框架和接头进行了静强度分析,并对加载框架进行验证试验。试验结果与强度分析结果对比表明:加载框架的静强度和其局部变形满足试验要求,可应用于起落架试验中。
The finite element method and traditional strength calculation method are used in the analysis of the loading framework for main landing gear test.The static strength analysis was carried out on the framework and the joint,respectively.The comparison of the test results and the strength analysis results show that the static strength of the framework and its local deformation meet the test requirements,and can be applied to the gear test.
