摘要: 用移动元胞自动机法(movablecellularautomata,MCA)计算了质量和速度相同、长细比不同的杆 式穿甲弹对侵彻过程影响的实例,计算结果与实验符合。移动元胞自动机法能较好模拟爆炸和高速穿甲侵彻 中材料瞬间的变形﹑破碎和飞散过程。Abstract: Themovablecellularautomata(MCA)methodwasimprovedandappliedtosimulatethe penetrationprocessoftungstenlongrodprojectilesinto27SiMnMotargetplates.Atanimpactvelocityof1000m/ s,thesimulatedresultsshowthatdifferentaspectratioscorrespondtodifferentmaximalpenetrationdepthsandthemaximalpenetrationdepthincr aseswiththeincreaseoftheaspectratio, buttheaspectratiosover25affectweaklypenetrationdepthunderthegivenexperimentalconditions.
