摘要
针对光学望远瞄准系统零位走动量的测量现状及发展趋势,结合零位仪的使用,对正切微动对零读数细分机构和正弦微动对零读数细分机构进行了研究和分析,提出了一种实用的高精度微动对零读数细分方法,设计了一种类正弦微动对零读数细分机构。在此基础上,研制了具体微动对零读数细分机构的主体结构,并对机构的误差进行了分析和计算,结果表明,此微动对零读数细分方法的理论估算结果的最大误差为0.001mm,角度测量分辨力可达到2.16″。
According to the present situation and development of testing variational momentum of the zero position for optical telescopic aiming system,the tangent mechanism and the sine mechanism are studied and analyzed with the use of zero position instrument.A new measurement mechanism is designed and a new micromotion reading subdivision method is putted forward.Based of these,the main structure of micromotion reading system is described and the errors are analyzed and calculated.The experimented results show that the actual maximum measurement of this mechanism is 0.001mm and the resolution is 2.16″.
