Novel wind tunnel balance loading sleeve and wind tunnel balance calibration method

The invention discloses a novel wind tunnel balance loading sleeve, which is connected with a calibration load applying mechanism in a wind tunnel balance calibration system through a three-dimensional force sensor, and can accurately obtain a transmission load, and by combining a position relation between a three-dimensional force sensor coordinate system and a to-be-calibrated wind tunnel balance coordinate system, actual load applied to the to-be-calibrated wind tunnel balance is obtained. The invention provides a brand-new wind tunnel balance body shaft system calibration method, displacement measurement errors and loaded load transmission errors are avoided, the complexity of a calibration system is reduced, the manufacturing cost is saved, meanwhile, the operation difficulty is reduced, and the method has a wide application prospect in the technical field of wind tunnel balance calibration. 本发明公开了一种新型风洞天平加载套筒，通过三维力传感器与风洞天平校准系统中的校准载荷施加机构连接，可精确获取传递载荷，再结合三维力传感器坐标系与待校准风洞天平坐标系的位置关系，进而得到施加在待校准风洞天平上的实际载荷，本发明提供
