A multi-component force combined calibration method

Abstract

The invention relates to a multi-component force combination calibration method, and belongs to the technical field of mechanical force value and force moment calibrations. The method comprises a Z-direction calibration (1), an X-direction calibration (2) and a Y-direction calibration (3); the Z-direction calibration locates above the horizontal plane and can move in positive and negative directions of the Z axis, the X-direction calibration and the Y-direction calibration locate on the horizontal plane, the X-direction calibration can move in the positive and negative directions of the Y axis, and the Y-direction calibration can move in the positive and negative directions of the X axis; and one to seven force values can be simultaneously loaded in a coordinating manner, and a combination calibration of multiple component forces F<X>, F<Y> and F<Z> and multiple component moments M<X>, M<Y> and M<Z> is achieved. Compared with the prior art, the multi-component force combination calibration method achieves calibrations of three component forces F<X>, F<Y> and F<Z> in different ranges and calibrations of three force moments M<X>, M<Y> and M<Z> through reasonable arrangement for thirteen forces in the X direction, the Y direction and the Z direction; and M<Z> can be separately loaded, and X-direction, Y-direction and Z-direction forces can move freely, so the combination calibration of the multiple components F<X>, F<Y>, F<Z>, M<X>, M<Y> and M<Z> is achieved, and a coupling state of multiple component forces in real life is really reflected.

Description

Technical field [0001] The invention relates to a calibration method, in particular to a multi-component force combined calibration method, belonging to the technical field of mechanical force value and torque calibration. Background technique [0002] At present, multi-component force measuring instruments can simultaneously detect the full information of three-dimensional space and have been widely used in aviation, aerospace and armored vehicle manufacturing and testing fields. For example, the vector thrust engine can provide fighters with maneuverability at large elevation angles, that is, the output of the vector engine and the transmission parts are all multi-component forces. The stress conditions of the key parts of the carrier aircraft and the helicopter and the supporting equipment are being tested and analyzed. Multi-component force is also applied, and the wheel hub is also subjected to multi-component force during the driving process. [0003] However, the current ca...

Problems solved by technology

[0003] However, at present, the calibration of multi-component force measuring instruments is basically limited to the calibration of force values ​​in one direction. The calibration of multiple components is achieved by changing the position of the multi-component force measuring instrument. The calibration process is cumbersome and cannot truly reflect the actual use process. Coupling measurement state of multi-component forces

Even if individual devices can achieve multi-component combined calibration of multi-component force sensors and test systems, relatively speaking, the range of each component (especially the lateral force and torque components) is relatively narrow, and cannot achieve separate torque loading, and cannot meet the requirements of multiple points. The calibration requirements of the force sensor, the research on the multi-component force combination calibration method is still blank in China
