摘　　要：提出了一种基于地震波触发的战斗部爆炸冲击波超压测试方法,该测试方法能可靠获取战斗部动爆冲击波超压峰值。采用提出的测试方法对着靶速度为0、535和980 m/s的战斗部空中爆炸冲击波分别进行了测试,并对战斗部动爆冲击波超压峰值测试结果和经验公式计算值进行了对比,定量分析了战斗部速度对冲击波压力场分布的影响。最后,在实测数据的基础上采用薄板样条插值方法重建了战斗部动爆冲击波超压三维可视化模型,为实战复杂环境下基于实测数据研究动爆冲击波特性提供了依据。A method for measuring the shock wave overpressure of blasting warhead explosion based on seismic wave triggering was proposed.By the proposed method,the peak overpressure of the blast wave from dynamic explosion of a warhead can be obtained reliably.The air explosion shock waves of the blasting warhead with the target velocities of 0,535 and 980 m/s were measured,respectively.And the measured results of the peak overpressure of the shock wave from dynamic explosion of the blasting warhead were compared with those by the empirical formula calculation.The influence of warhead velocity on the pressure field distribution of the shock wave was analyzed quantitatively.Finally,a three-dimensional visualization model for shock wave overpressure from dynamic explosion of the warhead was reconstructed by using the thin-plate-spline interpolation method.The reconstructed model can provide a basis for studying the characteristics of dynamic explosion shock wave based on the measured data in the complex environment of an actual combat.
