| 摘 要： | 为了提高杆式射流的速度,利用ANSYS/LS-DYNA有限元软件,对同长径比下的变壁厚球缺、圆锥组合罩与单球缺罩进行了射流形成的数值模拟。结果表明,组合罩形成的射流速度和射流长度都要好于单球缺罩。

| Abstract: | In order to improve the speed of rod jet,using the finite element software ANSYS/LS-DYNA,the formation of jet is simulatedu nder the combination liner charge of hemisphere and cone and the hemispherical liner charge with the same aspect ratio.The results showt hat the speed and length of jet formed by the combination liner charge is better than hemispherical liner charge. |
