| 摘 要： | 研制了可精确测量质量在100～1200 kg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%．

| Abstract: | 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. |
