摘要
为了进一步研究电枢出口速度的变化特性,以小口径C型固体电枢电磁轨道炮为研究对象,通过建立多变量灰色预测模型,来实现对电枢初速的拟合和预测,并对连续发射状态下电枢速度的变化及发射系统的性能进行预测和分析。分析结果表明,电枢初速的变化为先波动后稳定增加最后衰减的趋势,应用MGM(1,N)模型对于电磁轨道炮发射系统性能的研究具有重要意义。
In order to further study the variation characteristics of muzzle velocity of armature,the small caliber electromagnetic railgun was taken as research object.By means of building multi-variable grey forecasting model,the matching and prediction of muzzle velocity were realized,and the prediction and analysis of velocity variation were carried out under the state of continuous fire.The analysis results showed that the tendency of velocity variation is fluctuation at first,and then stable increase and attenuation at last.The application of MGM(1,N) model has important meaning for research on the property of electromagnetic railgun system.
