摘要: 为探讨弹头在肌肉组织中的运动规律,以明胶作为组织模拟物,结合明胶力学性质,在区别攻角和 偏角的情况下,建立同时考虑水平和垂直方向弹头侵彻明胶的二维运动模型。以7.62mm 普通弹和5.8mm 普通弹为杀伤元,根据龙格-库塔法原理对运动模型进行数值计算。同时,对2种弹丸侵彻明胶实验数据进行 了对比分析。分析结果表明,该二维运动模型能够准确合理的描述2种弹丸侵彻明胶的运动过程,具有一定 通用性,可为弹药设计和战伤救治提供理论参考。Abstract: Toresearchthemotionofabulletintothemusculartissue,thegelatinwasusedtosimulate themusculartissue.Basedonthepropertiesofthegelatin,atwo-dimensionalmotionmodelwasestablishedfortheprojectilepenetratingthegelatininwhichreflectingthedifferencebetweenattackangleandy wangle.Andthebulletmotionsinthehorizontalandverticaldirectionsweretakenintoaccountintheestablishedmotionmodel.
