This paper presents the development and preliminary application works of an automatic strain gauge balance static calibration system in ecs for 1m hypersonic wind tunnel of cardc
本文论述了cardc超高速空气动力研究所1m高超声速风洞配套的新型全自动六分量应变天平地轴系( ecs )校准系统的研制和初步应用研究工作。
The position measuring system was another important system in the new balance calibration system . to work out the calibration loads in the bcs of balance with the results of balance position measuring is the key technique to improve the veracity of the balance calibration results
通过天平空间位移测量并将地轴系校准载荷换算到天平体轴测量坐标系后再进行天平校准系数计算,是保证本文所研制的地轴系天平校准系统静校结果准确性的关键技术途径。
According to the study work of this paper , an automatic six - component strain gauge balance calibration system development scheme was put forwards : the system calibrates the balances in the ecs , and translates the loads to the bcs of the balances with measuring the balance ’ s position changes during the calibration
