Abstract

The invention discloses a dynamic simulation test bed frame for aircraft-landing-gear system braking. The dynamic simulation test bed frame comprises a test bed supporting frame, a loading device, a rolling wheel device, a driving device, a hydraulic source, a sensor assembly and a comprehensive control bed. According to the dynamic simulation test bed frame for aircraft-landing-gear system braking, as different loads can be evenly loaded by the loading device, different rotating speeds are provided by the driving device, and different road-surface limits are provided by the rolling wheel device, the test bed frame can be used for simulating aircraft-landing-gear braking dynamic processes under different working conditions. Compared with a traditional large-inertia-bed test bed frame, the dynamic simulation test bed frame has the advantages of being various in simulation working condition, accurate in simulation, low in cost and the like.

Description

technical field [0001] The invention belongs to the technical field of aircraft landing gear design and manufacture, and in particular relates to a braking dynamic simulation test bench for an aircraft landing gear system. Background technique [0002] In the design and manufacture of large aircraft, it is necessary to carry out ground simulation tests of the aircraft landing gear braking system. provide a test basis. [0003] The working environment of the aircraft landing gear brake system is harsh during the braking process, and the brake pads bear a large torque and wear severely. In real working conditions, it is difficult to obtain the key performance parameters of the aircraft landing gear braking system, which brings certain difficulties to the research and manufacture of the aircraft landing gear braking system. [0004] At present, high-energy inertial tables are mostly used in the tests of aircraft landing gear braking systems. The rotation of the wheel is driv...
