摘　　要：对射频5000发/min的弹鼓系统供弹过程中杆式穿甲弹主要零部件所受冲击力进行了数值计算,求解转动供弹和直线供弹工况下,药筒、弹托和钨芯上观察点的等效应力随时间变化情况。分析了零部件上最大应力峰值出现时刻和对应的安全系数,表明该杆式穿甲弹的结构强度符合现有供弹系统的使用要求,在转动供弹和直线供弹环节中零部件安全系数最低的均为药筒,但钨芯尾部在弹托包覆截面附近有明显的应力集中现象。分析结果为药筒和钨芯的加工检验工作及实弹射击试验提供了重要的理论依据。The impact force of the main parts of an APFSDS during the ammunition feeding process of an ammunition loading drum system with a cyclic rate of fire of 5000 rds/min is numerically calcula-ted.The equivalent stress of the observation points on the cartridge case,sabot and tungsten penetrator varies with time under rotating and linear ammunition feed conditions.The time when the maximum stress peak appears on the parts and the corresponding safety factor are analyzed.The results show that the structural strength of the APFSDS meets the requirements of the existing projectile feeding system,and the lowest component safety factor is the cartridge case in both the rotation feed and linear feed processes,however,the tail of the tungsten penetrator also has obvious stress concentration near the section of the sabot.The analysis results provide an important theoretical basis for the processing inspection of cartridge cases and tungsten penetrators and live firing tests.
