摘要
本文对火箭炮定向器作了模态分析试验,用导纳圆拟合法识别了它的模态参数,为研究定向器的动态特性提供了数据.
This paper describes the modal analysis test made for the director of a rocket launcher and the modal parameters identified with the mobility circle fitting method useful data are provided for the study of the dynamic properties of the director.
