Bullet Quality Evaluation Based on Combination Weighting and Gray Clustering
Aiming at the problems that bullet quality cannot be quantitatively evaluated and the utilization rate of bullet data is low,etc.a bullet quality evaluation model based on the subjective and objective combination weighting and gray clustering is proposed.The model uses linear weighting to combine the weights obtained by the subjective and objective weighting methods to improve the scientificity of the index weighting in the evaluation method,the membership function is constructed,and then the gray clustering method is utilized to obtain the comprehensive impact factors,so as to obtain the bullet.quality judgment results.The evaluation is carried out with 12.7 mm armor-piercing incendiary bombs,and a vertical target dispersion test is performed.The results show that the method has a good degree of discrimination,among which the density index R100,class Ⅰ(12.77 cm)<class Ⅱ(15.02 cm)<class Ⅲ(18.92 cm),the effectiveness of the method is verified.
