Three-dimensional steering mechanism load simulator and loading method therefor

Abstract

The invention relates to a three-dimensional steering mechanism load simulator and a loading method for the load simulator, belonging to the technical field of an airplane steering system test. The simulator consists of a base, an X-axis reciprocating straight-line mechanism, a Y-axis reciprocating straight-line mechanism, a Z-axis reciprocating straight-line mechanism, a bottom platform, a middle platform and a top platform. The method includes the steps that a front landing gear experimental prototype is firstly clamped on the base vertically, then the X-axis reciprocating straight-line mechanism, the Y-axis reciprocating straight-line mechanism and the Z-axis reciprocating straight-line mechanism are controlled to respectively drive the middle platform, the top platform and the bottom platform to do the left-and-right movement, the front-and-back movement and the up-and-down movement, so as to simulate the transverse frictional resistance and the lateral tire force on the airplane when front wheels of an airplane make a turn, namely, various working conditions of the wheels of the airplane in the static turning when the wheels of the airplane are under different ground loads can be simulated. The simulator and the method can achieve the turning test of the front wheels of the airplane under different conditions, and therefore, the practicability and the convenience are very strong, the whole set of device is simple in structure and high in safety.

Description

technical field [0001] The invention relates to a load simulation loading device and a loading method thereof, belonging to the technical field of aircraft steering system tests. Background technique [0002] Since the steering system has an important influence on the aircraft handling stability and safety in the research of aircraft dynamics, the development of the steering mechanism load simulation device has important value and application prospects. At present, my country's large aircraft industry has just started, and there is still a long way to go in the research on front wheel steering, especially how to carry out effective test demonstration on the designed nose wheel steering system, in order to obtain detailed test function parameters, It is extremely important to provide improvement or reference basis for subsequent design. [0003] In the research of steering load simulation device, the simulation of steering resistance is the key to the test bench. At present, ...

Problems solved by technology

But corresponding to the system test field of aircraft front wheel steering, since the tonnage of the aircraft itself is dozens of times higher than that of ordinary vehicles, and the difference in the structure and layout of the two, the above six resistance simulation devices cannot be directly applied to simulate the front wheel of the aircraft on the road. Static load on face turning
