Analysisand Validation for Characteristics of Air and Ground Shock Wave Near Field Explosion

针对近地爆炸冲击波传播规律复杂,三波点马赫波估计难,测点布置不准确,数据不能有效性分析等问题,理论分析了空中和地面冲击波传播特性,并根据文献数据拟合仿真三波点马赫波轨迹,给出马赫杆比例高度仿真图,并通过实爆实测数据理论值和实测值对比分析验证空中和地面冲击波传播特性,为以后的测点布置和数据分析提供了有效的理论依据。

Since propagation law of near explosion shock wave is complex, estimation of three wave point Mach wave is difficult and the data can not be analyzed effectively. In this paper, propagation characteristics of air and ground shock wave were analyzed in theory. The trajec- tory of three wave Mach wave was simulated and fit according to the literature data. The simulation diagram of Mach stem height proportion was shown. The propagation characteristics of the air and ground shock wave were analyzed by comparing real measured values with theoret- ical values. The conclusion provides an effective theoretical basis for the following measuring point arrangement and data analysis.
