摘　　要：本文运用波动力学对具有接头系统的冲击凿入效率进行了理论分析，给出了具有接头的冲击凿入系统传递函数Ｈ＿（ＪＰ）（Ｓ）＝Ｈ＿ｊ（Ｓ）·Ｈ＿ｐ（Ｓ）［此外Ｈ＿Ｊ（ｓ）为接头传递函数，Ｈ＿Ｐ（Ｓ）为凿入传递函数］，实际计算了刚性和等截面活塞两种具有接头凿入系统的能量传递效率，并分析了凿入系统各参数对能量传量传递效率的影响。Using Wave Mechanics theory,the percussive penetration efficiency with joint system has been re-searched,and the transfer function H_(JP)(s)=H_J(s)·H_P(s)[JH_J(s):the joint transfer function;H_P(s);the penetration transfer function] has been given. It have been made to compute the penetration efficiency of therigid or equal cross section(with rod)piston with joint system;and to analysis the influence of theparameters of penetration system on penetration efficiency.
