摘　　要：从刚性弹侵彻半无限靶板的理论出发 ,假设弹丸与钢筋仅在接触点发生相互作用 ,将问题简化为接触点在阻尼介质中受冲击荷载作用下的动力响应问题 ,建立了配筋对弹丸致偏效应的二维简化模型 ,模型结果与试验有较好的一致性 .Based on the analytical model of semi-infinite targets penetrated by rigid projectile, the assumption that the reaction between the projectile and the rebar occurs just at the contacting point, and the effect are simplified to be a point dynamic problem in damp medium. A 2D model for deflection of ogival nose projectile by rebar are developed. The deflection effects predicated with the model are in reasonable agreement with the test data. The rule of deflection by rebar are calculated and analyzed.
