The invention provides an aircraft landing gear uplock loading test device and method, and the device comprises a rack structure which is used for carrying and installing the whole device, and an installation support is fixed between the inner top and the side wall of the rack structure; an uplock to be tested is hinged to the mounting bracket; an uplock adjusting mechanism is mounted between the side wall of the lower part of the uplock and the mounting bracket; an uplock loading mechanism used for supporting and installing a lock ring is installed at the bottom of the rack structure, and a swing adjusting mechanism is installed between the top of the uplock loading mechanism and the side wall of the rack structure. A measuring clamp used for controlling the included angle and the distance between the axis of the upper lock and the axis of the lock ring is installed between the upper lock and the lock ring. The loading test device completely simulates the mounting type and the mounting state of the uplock on the aircraft to carry out a loading test, and the loading oil cylinder adopts a lower hinging type, can rotate by a required radius, and is used for simulating the folding and unfolding actions of the undercarriage in the locking and unlocking processes.
本发明提供了一种飞机起落架上位锁加载试验装置及方法,包括用于对整个装置进行搭载安装的机架结构,机架结构的内顶部和侧壁之间固定有安装支架;安装支架上铰接有待试验的上位锁;上位锁下部侧壁与安装支架之间安装上位锁调节机构;机架结构的底部安装有用于对锁环进行支撑安装的上位锁加载机构,上位锁加载机构的顶部与机架结构的侧壁之间安装有摆动调节机构;所述上位锁和锁环之间安装有用于控制上位锁轴线与锁环轴线夹角以及距离的测量夹具。此加载试验装置完全模拟上位锁在机上的安装型式和安装状态进行加载试验,加载油缸采用下铰接式,可以所需要的半径转动,用以模拟上锁和开锁过程中的起落架收放动作。
