[0003] Usually in this case, a lever is used to combine the unilateral non-examination landing gear, and then use a crowbar to form a support point for multiple landing gears, and then realize the three-point support of the aircraft, but this method cannot completely guarantee The combined non-assessment landing gear is equally loaded, and the structure is relatively large, so there are many restrictions on the design. At the same time, if there are more than two remaining landing gears, it will be difficult to realize single-point support of multiple landing gears in the form of lever combination. The loading of non-assessment landing gear will not be guaranteed

Embodiment Construction
[0022] Below in conjunction with accompanying drawing, the present invention will be further introduced, as figure 1 with figure 2 As shown, a test support system according to the present invention includes two cylinders 1 with the same structure, a piston 3 is arranged inside the cylinder 1, and the piston 3 is used for loading, and the piston 3 pushes the cylinder The body 1 is divided into an upper chamber and a lower chamber, the upper chamber communicates with the atmosphere, the lower chamber is filled with oil, and the lower chambers of the two cylinders 1 are equipped with connection ports 6. The two connecting ports 6 are communicated through the connecting pipe 12, so that the pressure in the lower chamber of each cylinder 1 is exactly the same. The top of the piston 3 is fixedly connected with the piston rod 2, and the piston rod 2 can be The piston 3 is driven to move along the length direction of the barrel 1 , and the displacement sensor 9 is arranged inside th...

The invention discloses a test support system, which comprises two cylinders with the same structure, a piston is arranged inside the cylinder, and the piston divides the cylinder into an upper cavity and a lower cavity, the upper cavity communicates with the atmosphere, and the lower cavity Filled with oil, there are connecting ports on the lower chambers of the two cylinders, the two connecting ports are connected through the connecting pipe, the top of the piston is fixedly connected with the piston rod, the piston rod can drive the piston to move along the length of the cylinder, the piston Displacement sensors are arranged inside the rod. The system of the present invention is compact in structure and requires less space for implementation; it can conveniently realize the combination of two or more landing gears; it can ensure that the landing gears at each support point are exactly the same in the test process It achieves the static support state of multiple landing gears; the main carrier is hydraulic oil, which has a large carrying capacity and is easy to expand.
Description
technical field [0001] The invention relates to the technical field of aircraft structure tests, in particular to a test support system. Background technique [0002] In the aircraft structure test, choosing a reasonable aircraft support method is the premise and guarantee for the high-quality completion of the test. For an aircraft with multiple main landing gears, the number of main landing gears on the left and right sides is two or more. During the test, Generally, the landing gear is used as the main test point for test loading, and the non-test landing gear is used as the aircraft support point. For the multi-main landing gear aircraft test, the test landing gear is generally one or a part of the main landing gear (symmetrical on both sides), then The remaining main landing gear and the front landing gear will be used as aircraft test support points. In the aircraft structure test, three points of support are generally formed vertically through the landing gear, but if...
