Abstract
Strain gauge balances are basic equipment for wind tunnel tests. With the continuous and rapid development of material, design and processing technologies, temperature effects have become one of the main factors affecting the test ability and reliability of wind tunnel strain gauge balances [1]. Facing the developing technical requirements of wind tunnel tests, CARDC has carried out the research on strain gauge matching compensation technology around the temperature effect correction for a wind tunnel strain gauge balance and has achieved preliminary successful application. Based on the temperature performance test of strain gauge and temperature optimization, this technology realizes the temperature effect compensation control of a wind tunnel strain gauge balance. It has the characteristics of high compensation accuracy and good overall reliability. The research is of positive significance to improve the development technical level of domestic wind tunnel balances.
