Multi-component force combination 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.

technical field [0001] The invention relates to a calibration method, in particular to a multi-component force combined calibration method, and belongs to the technical field of mechanical force value and torque calibration. Background technique [0002] At present, multi-component force measuring instruments can simultaneously detect full-force information in three-dimensional space and have been widely used in manufacturing and testing fields such as aviation, aerospace and armored vehicles. For example: the vector thrust engine can provide fighter jets with maneuverability at high elevation angles, that is, the output of the vector engine and the transmission parts are all subjected to multi-component forces. The test and analysis of the stress status of the key parts of carrier-based aircraft and helicopters and supporting equipment The application is also multi-component force. When the car is running, the wheel hub is also subjected to multi-component force and so on. ...

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
