【Abstract】 A newlydeveloped static calibration system of wind tunnel balance is introduced, which is large loaded, automatic and high accuracy. The principle of static calibrating for wind tunnel balance, the frame of the calibration system, the testing principle of sixdegreeoffreedom power and resetting control system are discussed in detail. The results of unit experiment show that the resolution of threedegreeoffreedom linear displacement is 2 μm, the resolution of threedegreeoffreedom angle is 1″, the resetting precision of linear displacement is better than 6 μm, and the resetting precision of angle is better than 3″.更多还原
