摘要
以某型飞机机翼整体油箱壁板为研究对象,考虑非加载边支持结构的不同弹性约束方式对加筋壁板稳定性的影响,采用MSC/Nastran软件及SDA1.1软件,计算分析了加筋壁板受压时的屈曲临界应力。通过对计算结果进行比较分析,得出了适合该型飞机机翼油箱壁板稳定性的计算规律。
After research on panel of wing integrated fuel tank of a certain type aircraft, the influence of different elastic boundary of non-loading border support structure to stability of reinforced panel is considered. Furthermore, the flexure critical stress during reinforced panel is pressed is calculated and analyzed by using MSC/Nastran and SDA1.1. Comparing the results of two methods, the calculation rule for stability of reinforced panel of wing integrated fuel tank is finalized.
