The invention introduces an undercarriage structure bearing test device. The undercarriage structure bearing test device comprises a test platform, a test piece, a vertical load loading assembly, a course load loading assembly, a lateral load loading assembly, a traction force loading assembly and an ejection force loading assembly. According to the invention, a certain type of shipboard aircraft landing gear is used as a test piece, so that the bearing condition of the aircraft landing gear during catapult-assisted take-off and landing of an aircraft is simulated in a laboratory; the hydraulic actuator cylinder is adopted for loading, the load is stable, and the continuity is good; the arrangement and installation of the test device can accurately simulate the stress condition of the undercarriage during catapult-assisted take-off and landing of the aircraft, meanwhile, the construction and installation are simple, the test scale is reduced, and the test cost is saved.
本发明介绍了一种起落架结构承载试验装置,包括试验平台、试验件、垂直载荷加载组件、航向载荷加载组件、侧向载荷加载组件、牵制力加载组件和弹射力加载组件。本发明以某型舰载机起落架为试验件实现了在实验室中模拟飞机弹射起飞及降落时飞机起落架的承载情况;采用液压作动筒加载,载荷平稳,连续性好;试验装置的布置和安装可以准确模拟飞机弹射起飞及降落时起落架的受力情况,同时施工安装简单,降低了试验规模,节约试验成本。
