The invention relates to the technical field of flexible joint simulation experiments, and discloses a device for examining the working condition of a flexible joint of an aircraft conduit at a bent pipe, and the device comprises multiple straight pipes, the adjacent ends of the multiple straight pipes are used for installing the flexible joint, and the multiple straight pipes can form a straight-through pipe; the first clamping block is used for fixing one section of the straight pipe; the second clamping block is used for fixing the other section of adjacent straight pipe, and the second clamping block can slide relative to the first clamping block so that the adjacent sections of straight pipes can be staggered; a bent pipe in actual working conditions is replaced by the straight pipe, working condition simulation of the flexible joint at the bent pipe can be formed, finally, working condition pressure is introduced into the communicated straight pipe for simulation, assessment of the flexible joint can be realized, the straight pipe is simple to process, the assessment test cost is low, the connection operation of the flexible joint is simple, and the test efficiency is high. And the operation difficulty of the test is effectively reduced.

    本发明涉及柔性接头模拟实验的技术领域,公开了一种飞机导管柔性接头在弯管处工况的考核装置,包括:直管,多节所述直管相邻的一端用于安装柔性接头,且多节所述直管能够组成一根直通管;第一夹块,用于固定其中一节所述直管;第二夹块,用于固定其中另一节相邻的所述直管,所述第二夹块能够相对所述第一夹块滑动,以使相邻节段的所述直管错位;通过直管取代了实际工况中的弯管,能够形成柔性接头在弯管处的工况模拟,最后向连通的直管内通入工况压力进行模拟,则能够实现柔性接头的考核,直管加工简单,考核试验的成本低,且柔性接头的连接操作简单,有效降低了试验的操作难度。
