文中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,开展了战术导弹模型小量程滚转力矩天平结构研究、灵敏度精细化设计与有限元分析、灵敏度干扰量计算和强度校核。给出了天平输出灵敏度精细化设计结果,并与有限元分析结果进行了比较。

Compared with other components of load, roll torque component of the load of wind tunnel model for tactical missile is the characteristic of a small amount. In this paper, research was carried out on a small range of roll torque balance structure for a model of tactical missile, sensitivity of fine design, finite element analysis, the sensitivity of interference quantity calculation and strength check. The output sensitivity of fine scales design results was also give, and the results were compared with that of finite element analysis.
