摘要
研制了可精确测量质量在100-1200kg范围内导弹等飞行体转动惯量的大型测试系统。利用可展开式测量臂结构,实现了一次工装就可以测量出导弹对3个轴的转动惯量,从而有效降低了多次安装带来的定位误差。对影响系统测量精度的误差因素进行了定量分析。对标准样件进行了实测,各轴的转动惯量测量误差均小于0.1%.
A large system used for measuring inertia moment of missile with the mass ranged from 100 kg to 1 200 kg was developed, The measurement of missile's inertia moment relative to three axes was realized by an expandable measuring arm under only one-step installation having less the positioning errors than multi-step installations. The main factors affecting precision were also analyzed quantitatively. The inertia moment of standard body was measured, and the results show that the error is less than 0.1% in measuring inertia moment relative to every axis.
