Embodiment Construction

[0092] This embodiment is a landing gear stiffness simulation device, which includes a working platform 1, 4 sets of oil cylinders 4, 8 universal joints 2, a base 5 and 4 sets of adjustable length rods 3. Among them, the 8 universal joints are divided into 4 groups, which are respectively installed on the four corners of the working platform 1 and the four corners of the base 5 . The universal joints on the four corners of the working platform are respectively connected with one end of an adjustable length rod 3; the other ends of the connecting rod are all threaded with the upper end of an oil cylinder 4; The lower ends are all connected with the universal joints on the four corners of the base. Through the above connections, four stiffness simulation devices are constructed.

[0093] The oil cylinder 4 includes a piston 6 , a cylinder body and an end cover 7 , a displacement sensor 8 and a nozzle 9 . The hydraulic cylinder block 7 is a hollow rotary body with end caps at b...

Abstract

The invention relates to an undercarriage rigidity simulating device and method. The device comprises a workbench, four sets of oil cylinders, eight universal joints, a pedestal and four sets of length adjustable rods. The eight universal joints are divided into four groups, and are mounted in four corners of the workbench and four corners of the pedestal respectively, and each universal joint positioned in the corner of the workbench is connected to one end of one length adjustable rod; the other end of each length adjustable rod is connected to the upper end of one oil cylinder; and the lower end of each oil cylinder is connected to one universal joint positioned in the corner of the pedestal. Four rigidity simulators support the workbench and inflated with the needed pressures P1, P2, P3 and P4 respectively to achieve a needed simulation rigidity, rigidity simulation in space is completed, the device and method are characterized by small size and compact structure, object rigidity simulation can be carried out in a wide range, and the spatial position of an object can be measured.

Description

[0001] Factory 514 Song Jieshu 18681985290 technical field [0002] The invention relates to the field of landing gear simulation, in particular to an object stiffness simulation device. Background technique [0003] At present, in order to simulate the stiffness of different objects during different tests, it is necessary to produce test fixtures corresponding to the stiffness and structural requirements of the test. The test piece for simulating stiffness and structural requirements is single, and the test piece tooling for simulating stiffness and structural requirements is only for one test state. At present, there is no equipment or device that can carry out the tooling that needs to be tested for different object stiffness. If you want to complete the test with different rigidity requirements for test fixtures, you need to prepare a variety of test fixtures with different stiffnesses and structures. In this way, many test fixtures with different test stiffnesses are ...
