Abstract

The invention relates to an infinite space standard vector force calibration device which is used for calibrating the six component forces of a six-component measurement bench of an aero-engine and can be used for calibrating the three component forces of a three-component sensor. The device comprises a gantry frame (1), and three calibration components for generating calibration forces are installed on the gantry frame (1). In the process of calibration, the loading force of a hydraulic loading oil cylinder (4) in a single calibration component can be compared with the calibration force generated by a single-component sensor for calibration on an engine test bench, or, the resultant force of the loading forces of the hydraulic loading oil cylinders (4) in multiple calibration components can be compared with the resultant force measured for calibration on the engine test bench. The influence of unit calibration on the component forces of a measurement system is avoided. The accuracy of measured values of the component forces of the vector engine test bench is improved greatly. Accurate measurement data can be provided for the magnitude, direction and action point of the vector force of a thrust-vectoring engine. An experiment basis can be provided for the study of a thrust-vectoring engine.

Description

technical field [0001] The invention is a stepless space standard vector force calibration device, which belongs to the field of product structure design. This setting is mainly used for the calibration of the six component forces of the aero-engine six-component force measuring bench, and can also be extended to the calibration of the three component forces of the three-component force sensor. Background technique [0002] The vector thrust is a space vector force generated by the vector nozzle engine, and its force value is measured on a six-component force measurement bench. The test bench is called the aero-engine six-component force measurement bench. Before the aero-engine test bench is put into use, the six-component force measurement system needs to be calibrated. The purpose of calibration is to confirm the accuracy of the measuring components on the six-component force measuring bench. [0003] The general calibration process is to use a simulated engine with th...
