摘　　要：运用AUTODYN2D软件模拟两段式平头长杆体侵彻靶板的过程。结果表明,在杆体初始动能相同时,Ⅰ型刚性连接器连接的长杆体的后段材料选用铀时侵彻深度大,而填充缓冲材料的Ⅱ型连接器连接的长杆体的前段材料选用铀时侵彻深度更大。从而得出:分段式长杆体前、后段材料以及连接器材料不同,侵彻效率不同;Ⅱ型连接器连接的长杆体比Ⅰ型连接器连接的长杆体的侵彻效率低。In order to study the influence of the material of the front and rear segment of the segmented long rod and the material and type of connector in segmented long rod on the penetration efficiency of the target,the software of AUTODYN2D was used to simulate the process of two-stage flat head segmented long rod penetrating target.The results show that under the same condition of the initial kinetic energy of the rod,the front segment material of long rod connected by the type I rigid connector has a greater penetration depth when the uranium was selected.And the rear segment material of the long rod body connected by the typeⅡconnector filled with the buffer substance,the penetration depth is greater when uranium is selected.It is concluded that,the penetration efficiency of the segmented long rod is unequal when the materials of front segment,rear segment and connector is different;the penetration efficiency of the segmented long rod is unequal when has different type of connector;the penetration efficiency of segmented long rod with typeⅡconnector is lower than segmented long rod with typeⅠconnector.
