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.
