Abstract:
To research the influencing factors of the armature muzzle velocity and the identification method for armature transition of electromagnetic rail launching systems,nonlinear GM(1,N)grey models of interior ballistic theoretical calculation and experimental data are established based on the analysis of grey relations entropy.The coordination of influencing factors is quantitatively analysed through the comparison of the values and polarity of driving coefficients.The results show that:in electromagnetic rail launching experiments,the charge voltage promotes the armature muzzle velocity mostly,and the diameter of the armature takes second place;the position of the measuring velocity target inhibits the armature muzzle velocity mostly,and the mass of the solid armature takes second place;there is a certain inherent positive connection between the weight coefficient of the armature mass and armature transition.
