The invention provides an aircraft main landing gear simulation test device, a test load vehicle and a control method, relates to the technical field of flight test devices, and solves the technical problems that a test result has errors and is low in precision due to the fact that a main landing gear of a test load vehicle cannot rise and fall along with load change. The aircraft main landing gear simulation test device and test load vehicle comprises a main landing gear main body, a left wheel assembly and a right wheel assembly, wheel carrier upper joints, wheel carrier lower joints and hydraulic driving mechanisms are arranged between the left wheel assembly and the main landing gear main body, and wheel carrier lower joints and hydraulic driving mechanisms are arranged between the right wheel assembly and the main landing gear main body. The wheel carrier upper joints are rotationally connected to the two ends of the main undercarriage body, one ends of the wheel carrier lower joints are rotationally connected with the wheel carrier upper joints, the other ends of the wheel carrier lower joints are connected with the left wheel assembly or the right wheel assembly, and the hydraulic driving mechanisms are connected between the wheel carrier upper joints and the wheel carrier lower joints. The invention is used for providing the aircraft main landing gear simulation test device capable of improving the accuracy of the test result and testing the load vehicle.

    本发明提供了一种飞机主起落架模拟测试装置、测试负载车及控制方法,涉及飞行测试装置技术领域,解决了测试负载车主起落架不能随负载变化而升降,导致测试结果存在误差,精度低的技术问题。该飞机主起落架模拟测试装置及测试负载车包括主起落架主体、左轮总成和右轮总成,左轮总成与主起落架主体之间、右轮总成与主起落架主体之间均设置有轮架上关节、轮架下关节以及液压驱动机构,轮架上关节转动连接在主起落架主体的两端,轮架下关节的一端与轮架上关节转动连接,轮架下关节的另一端与左轮总成或右轮总成连接,液压驱动机构连接在轮架上关节与轮架下关节之间。本发明用于提供一种提高测试结果准确性的飞机主起落架模拟测试装置、测试负载车。
