摘　　要：以Dytran程序为模拟平台,将美军的碎片模拟弹作为冲击源,地炮防盾为承载体,建立了碎片与防盾接触的有限元模型,并以碎片模拟弹的质量和速度为变量,模拟了不同质量、速度的碎片对防盾的非线性冲击过程,证明了我地面火炮的防盾基本上不具备防美军弹丸碎片冲击的能力。The FEM using contact between the fragment and shield is built on dytran software as simulation platform,in which the FSP of USA is impacting object and shield the artillery is the bearing object . The nonlinear process of fragments of different mass and different velocity impacting the shield is simulated with the mass and velocity of the FSP as variables. The simulation proved that our artillery shield cannot bear the impact of the fragments of USA.
