摘要
Abstract
To investigate the relationship between the diameters of projectile and the maximum temporary cavity diameters of target, the similarity model of steel ball penetrating into gelatin was built based on the dimensional analysis. The similarity law of the maximum diameters of the temporary cavity produced by the steel ball penetrating into the gelatin was analyzed,and a scale down experiment method and prediction formula of the maximum temporary cavity diameter based on the similar theory were obtained. The wound experiments were conducted,in which the steel balls with different diameters were used to penetrate into gelatin. The results indicate that the scale down experiment and prediction formula of the maximum temporary cavity diameter have high prediction accuracy under special conditions.关键词
