The invention discloses a test fixture for fixing a high-strut undercarriage on a test bed, and belongs to the field of aviation undercarriage tests. The test fixture comprises a bearing plate assembly, a side support assembly, a joint assembly and a front support assembly. A connector assembly is installed on one side of the bearing plate assembly and used for being connected with a folding and unfolding assembly and a butt joint lock shell of the undercarriage. The top of the bearing plate assembly is connected with the test bench. The two side supporting assemblies are installed on the side wall of the bearing plate assembly, and the top faces of the side supporting assemblies are fixedly connected with the bottom face of the test bed. The front supporting assembly is installed on one side of the upper end of the bearing plate assembly and used for being connected with a heading supporting rod of the high-strut landing gear. And the joint assembly and the front support assembly are matched to vertically mount the high-strut landing gear on one side of the bearing plate assembly. The test fixture truly simulates the installation environment of a high-strut undercarriage and a fuselage, is used for carrying out laboratory integrated test on an aircraft undercarriage system, an aircraft wheel brake and a brake control subsystem, and solves the problem that laboratory integrated test of each system is difficult to realize in the prior art.
本发明一种将高支柱起落架固定在试验台上的测试夹具,属于航空起落架试验领域。测试夹具包括承载板组件、侧撑组件、接头组件、前撑组件。承载板组件一侧安装有接头组件,用于连接起落架的收放组件和对接锁壳。承载板组件的顶端连接试验台。两组侧撑组件安装于承载板组件的侧壁,侧撑组件的顶面与试验台底面固定连接。前撑组件安装于承载板组件上端一侧,用于连接高支柱起落架的航向撑杆。接头组件、前撑组件配合将高支柱起落架竖直安装于承载板组件一侧。该测试夹具真实模拟高支柱起落架与机身的安装环境,用于对飞机起落架系统、机轮刹车、刹车控制分系统进行试验室集成测试,解决了现有技术中难以实现各系统试验室集成测试的问题。
