| 摘 要： | 针对风洞天平体轴校正与地轴校正之间的差别 ,建立了一种修正方法。该方法根据加载后的变形测量将地轴校正的载荷修正为体轴系的载荷 ,以得到体轴系天平公式。为用地轴校正台获得体轴校正结果开辟了一条新途径。对比结果表明该修正方法是行之有效的。

| Abstract: | Countering the difference between the calibrations with repositioning and non repositioning of wind tunnel balances, a new load correction method is developed. By means of the deflection measurement this method is able to correct the component loads in calibration with non repositioning to the component loads of body axes, and further, obtain the balance equations in body axes; thus it starts a new approach to carry out the body axes calibration in non repositioning calibration rig. The comparison shows that the method suggested is effective. |
