微量滚转力矩天平测量技术研究∗

摘要

针对战术导弹风洞试验模型滚转力矩分量载荷相对于其它分量载荷是一个小量的特点，文中开展了战术导弹模型微量滚转力矩天平总体方案设计、结构设计、灵敏度设计、安全限位设计、干涉分析及固有频率计算等研究，并应用其研究成果完成了一台微量滚转力矩天平的研制，给出了天平静态校准结果。校准结果表明，天平设计方案合理可行。%Compared with other component load, the roll torque component load of wind tunnel model for tactical missile is a small amount. In this paper, overall scheme design, structure design, sensitivity design, safety limit design, interference analysis and calculating natural frequency, ect. for micro-scale roll moment balance were researched, and the findings were applied to develop a micro-scale roll moment balance, and the balance’ s static calibration results were given. Calibration results show that the design is reasonably practicable.
