High Precision Measurement Technology of Electromagnetic Gun of Rail Spacing
摘要
Abstract
During the electromagnetic launching process,the high speed sliding electrical contact about armature-rail is closely related to the accuracy of the rail spacing.Accurate measurement about the rail spacing can effectively guide the design of armature and researching for the matching about armature-rail.According to the cross-sectional,irregularly shaped characteristics,and the changing shape of the railgun.An high-precision measurement method for spacing size was proposed based on the angular bisector characteristic.In this method,the spatial position of two rails was divided into two segments that interest at a certain degree.The angular bisector was adopted as the measurement reference,and a measurement points were taken.The perpendicular lines of the two rails were drawn through the measurement point.The line connecting the two perpendicular feet was defined as the orbital spacing value.Through prototype design,comprehensive system error analysis,and comparative verification,a certain caliber railgun spacing engineering measurement was carried out.The results show that the measurement error is≤0.05 mm,which satisfies the accuracy requirements.By obtaining accurate data of the rail spacing,an indispensable measurement method can be provided for numerical modeling,assembly process,and performance testing about electromagnetic launch devices.Thereby promoting the engineering application of railgun weapons.关键词
