摘　　要：应用AUTODYN软件对FAE装置燃料近区的抛撒进行了数值模拟,给出爆炸载荷下燃料抛撒的速度曲线,得到燃料抛撒的初始速度和最大速度,数值模拟与理论计算结果一致性较好。结果表明,在满足结构强度要求的前提下,外壳体材料的屈服强度和厚度越小,越有利于提高燃料的抛撒速度;内壳体材料的选取不仅要考虑材料的屈服强度,还要考虑材料的密度等因素。Based on the AUTODYN program,the fuel near-field dispersal velocity of FAE was simulated.The fuel dispersal velocity curve under explosive load,the initial and maximum fuel dispersal velocity were obtained.The simulation results perfectly accorded with those gained from theoretical calculation.The results showed that the smaller the yield strength and thickness of outer shell,the higher the fuel dispersal velocity.For the inner shell,the factor of density should also be considered besides the yield strength.
