为得到飞机中外对接件在载荷状态下的应力分布情况,合理的对其寿命进行估算,采用ANSYS软件对飞机中外对接件进行有限元分析并与试验值对比,得到应力分布情况,应用局部应力应变法做寿命的估算,其结果为结构细节改进和评价构件的疲劳分析提供依据.
In order to obtain the stress distribution of docking part under the load condition and its fatigue life, ANSYS software was adopted to make finite element analysis, the analyzed results are compared with its experimental values, and its fatigue life was estimated by local stress-strain method. The result provides evidence for structure improvement and the fatigue analysis of components.
