Universal flexible part

Abstract

The invention discloses a universal flexible part. A shell is of a hollow cuboid structure without a top surface and a bottom surface; a first main leaf spring and a second main leaf spring are the same in structure, the first main leaf spring comprises transverse leaf springs and axial leaf springs, two pieces of the axial leaf springs are arranged, and the two pieces of the axial leaf springs are fixedly connected to the transverse leaf springs respectively and are perpendicular to the transverse leaf springs; containing grooves used for containing the axial leaf springs are arranged in theleft surface, the right surface, the front surface and the rear surface of the shell; and the containing grooves in the left surface and the right surface of the shell are arranged at the tops of theleft surface and the right surface of the shell, and the containing grooves in the front surface and the rear surface of the shell are arranged at the bottoms of the front surface and the rear surfaceof the shell; the two pieces of the axial leaf springs of the first main leaf spring are matched with the containing grooves in the left surface and the right surface of the shell respectively, and the two pieces of the axial leaf springs of the second main leaf spring are matched with the containing grooves in the front surface and the rear surface of the shell respectively; and the four piecesof the axial leaf springs are fixedly connected to the left surface, the right surface, the front surface and the rear surface of the shell through supporting leaf springs respectively.

Description

technical field [0001] The invention relates to the technical field of thrust measurement, in particular to a universal flexible part. Background technique [0002] Engine testing and testing technology is an important part of solid propulsion technology, and thrust vector eccentricity is an important parameter that needs to be measured in engine testing and testing. To study the eccentricity of the engine thrust vector, a large number of repeated experiments are required, and it is impossible to put all these experiments into flight tests. The main reason is that the flight test has high cost, long period, small amount of information harvested, risky, and requires a lot of manpower. This requires the ground test of the engine. The ground test of the engine refers to the static test of the system on the ground according to specific conditions and environmental requirements, and obtains information describing various performance indicators of the system, so as to solve the p...

Problems solved by technology

[0003] With the development of domestic engine testing technology, some large engines have adopted thrust vector control devices. At present, multi-component force models and multi-component force test benches are mainly used to measure thrust vector at home and abroad, and the six-component force measurement method is more commonly used. , six-component force vector thrust measurement technology, the moving frame needs to be connected with the fixed frame through the connecting parts, and the connecting parts are required to be universally flexible and almost frictionless in order to realize the authenticity of the simulation and improve the simulation accuracy. Currently, the universally flexible The technology of the parts is not yet mature. The existing universal flexible parts are either complicated in structure, high in cost, or have a large friction coefficient, which is not suitable for the use of the existing six-component force test bench.
