The invention particularly relates to a strength test loading structure for an inclined airtight floor in a main landing gear cabin of an aircraft, which is supported by a fixed bottom plate, and is characterized in that a frame formed by hinging a central wing simulation plate, a horizontal airtight floor simulation plate, a vertical skin simulation plate and an inclined skin simulation plate is connected with the edge of the inclined airtight floor; a loading actuator cylinder is utilized to apply lateral shear load in a reciprocating manner, and bottom constraint edges, top constraint edges, vertical constraint edges and inclined constraint edges on a central wing simulation plate, a horizontal airtight floor simulation plate, a vertical skin simulation plate and an inclined skin simulation plate are matched with a loading cover plate to constrain a loading air bag; the loading air bag is used for applying airtight load, the loading cover plate is hinged to the top restraining edge, the vertical restraining edge and the oblique restraining edge, the problem that airtight load loading and lateral shear load loading interfere with each other can be avoided, and accurate airtight load loading and lateral shear load loading of the oblique airtight floor are guaranteed.
本申请具体涉及一种飞机主起落架舱内斜气密地板强度试验加载结构,设计以固定底板进行支撑,以中央翼模拟板、水平气密地板模拟板、垂向蒙皮模拟板、斜向蒙皮模拟板铰接构成的框架连接斜气密地板的边缘,利用加载作动筒往复施加侧向剪切载荷,以及以中央翼模拟板、水平气密地板模拟板、垂向蒙皮模拟板、斜向蒙皮模拟板上的底部约束边缘、顶部约束边缘、垂向约束边缘、斜向约束边缘配合加载盖板对加载气囊进行约束,利用加载气囊施加气密载荷,且加载盖板与顶部约束边缘、垂向约束边缘、斜向约束边缘间铰接,可避免气密载荷加载与侧向剪切载荷加载相互干涉影响的问题,保证对斜气密地板气密载荷加载、侧向剪切载荷的准确加载。
