Problems solved by technology

The force point of the follow-type compensating body-shaft balance calibration system is too close to the balance, so the accuracy is low; It is difficult to determine the exact position of the force point, so the accuracy is low; the standard balance of the double-balance non-compensated body-shaft balance calibration system also needs to be calibrated, and the error of the calibrated balance will also increase, so the equipment structure will be more complicated. The range and accuracy of standard balances are very demanding, and some require a complex system for calibrating standard balances

Description

technical field [0001] The invention relates to the technical field of aeronautical aerodynamic wind tunnel tests, in particular to a set of high-precision full-automatic zero-return compensation type body shafting balance calibration system capable of obtaining the working formula of the balance. Background technique [0002] The wind tunnel balance is one of the key equipments in the wind tunnel force test, and the accuracy of the balance directly affects the accuracy of the wind tunnel test data. The balance is a measuring instrument, and it cannot be used without calibration. The calibration of the balance is completed through the balance calibration system. The balance calibration system is a necessary condition for providing high-precision and high-accuracy balances. The accuracy of the balance depends on the accuracy of the calibration system. Therefore, all wind tunnel experiment units attach great importance to the development of high-precision balance calibration ...
