摘要
为测量滚转力矩为g·cm量级的小不对称烧蚀弹头的滚转力矩系数 ,采用了以气浮轴承支撑模型 ,用天平来测量模型上的滚转力矩的测量方法。天平的设计载荷为 0 0 2N·m。试验表明 :所研制的气浮天平既具有常规天平经济、直观的优点 ,同时又具有比常规小滚转力矩天平高一个量级的测量精度 ,能用于 1 0 - 6级测量。
In order to measure the tiny roll moment(g·cm grade)coefficient of small unsymmetrical burned warhead, the gas-bearing is used for model support and the balance is used for the roll moment measurement of the model. The designed load is 0.02N·m. The test shows that the gas-bearing-balance has not only advantage of economy and intuition as conventional balances, but also one grade higher accuracy than that of the conventional ones. The resolution is up to 10 -6 .
