摘要
Abstract
In this paper, the measurement beam of axial force of wind tunnel strain gauge balance was analyzed by contrasting the traditional T beam and thwart II beam. Based on the analysis, we put forward the improvement on thwart II beam, and the improved beam is optimized by using the FEA soft . The beam reduces the Y-interaction on X availably, benefiting the stability improvement of axial force. A balance on the high speed wind tunnel force test of an airplane model applies the thwart II beam. The static calibration accords with the results of the analysis, and the balance is in order and stable during the wind tunnel test.
