Abstract

The invention relates to a single-vector multi-element loading sleeve device of a wind tunnel balance and a using method thereof. The device comprises a base, a loading sleeve outer ring, a loading sleeve middle ring, a loading sleeve inner ring, a loading sleeve lower hem and a wind tunnel balance, wherein the loading sleeve outer ring comprises an outer sleeve ring and an inner sleeve ring, twosides of the outer sleeve ring are rotationally connected with a lower hem of a loading sleeve, the inner sleeve ring is rotationally connected into the outer sleeve ring, the loading sleeve middle ring is inserted into the inner sleeve ring, the loading sleeve inner ring is slidably connected into the loading sleeve middle ring, threads are formed outside the loading sleeve inner ring, outer threads of the loading sleeve inner ring are connected with a baffle ring, a side surface of a baffle ring abuts against the loading sleeve middle ring, one end of the wind tunnel balance is inserted intothe loading sleeve inner ring, the other end of the wind tunnel balance is sleeved with a supporting rod, and the supporting rod is erected on the base. The device is advantaged in that the single-vector multi-element precise calibration requirement of the wind tunnel balance is met.

Description

technical field [0001] The invention relates to the technical field of wind tunnel balance experimental equipment, in particular to a wind tunnel balance single-vector multi-element loading device and a method for using the same. Background technique [0002] After the wind tunnel balance is manufactured and before the wind tunnel test, static calibration is required to obtain its service coefficient. The static calibration of the balance is divided into unit calibration and multi-element calibration according to the loading method. Among them, unit calibration refers to when other components are zero (or In the case of constant), each component is loaded separately in turn, and the balance use coefficient is obtained item by item; the balance multi-component calibration is to load each balance component at the same time, and the balance use coefficient is obtained by using the multi-element calibration algorithm. [0003] Although in the calibration of the balance unit, the...
