Universal flexible force-measuring component

Abstract

The invention provides a universal flexible force-measuring component. The universal flexible force-measuring component comprises a first connecting plate, a hydraulic cylinder, an adapter, a first universal flexible member, a force-measuring sensor and a second universal flexible member which are sequentially connected with each other. According to the universal flexible force-measuring componentprovided by the invention, the two universal flexible members are arranged, so that the universal movement of the force-measuring component is realized, thus the measurement of the vector force of asix-component test bed is realized, the implementation accuracy is improved, and the structure is simple.

Description

technical field [0001] The invention relates to the technical field of thrust measurement, in particular to a universal flexible force measurement assembly. 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...

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 force measuring component, and the force measuring component is required to be universally flexible and almost frictionless, so as to realize the authenticity of the simulation and improve the simulation accuracy. The technology of directional flexible force measuring components is not yet mature. The existing universal flexible force measuring components are not suitable for the use of the existing six-component force test bench due to their complex structure, high cost, or large friction coefficient.
