摘要:
该文采用冲击波相似率和量纲分析法研究了冲击波压力持续时间(SWPD)在靶板中的衰减特性,获得了SWPD在靶板中的理论衰减模型。结果表明,当靶板材料及飞片速度确定时,在靶板中某传播距离处的SWPD与靶板撞击面中心处的SWPD之比是传播距离与飞片厚度之比的函数; 当传播距离和飞片厚度的比值不变时,该传播距离处的SWPD与靶板撞击面中心处SWPD的比值也不变。利用数值仿真方法分析了SWPD在无氧铜材料靶板中的衰减特性,获得了SWPD衰减模型的定量分析结果,验证了该文理论衰减模型的有效性。
Abstract:
The shock wave similar rate and the dimensional analysis method are adopted to investigate the attenuation characteristics of the shock wave pressure duration(SWPD)on the target board,and the theoretical attenuation model of the SWPD is obtained.Results show that when target board materials and the velocity of flyers are determined,the ratio of SWPD at a certain propagation distance on the target plate to the SWPD at the center point on the impact surface is a function related to the ratio of the propagation distance and the flyer's thickness.When the ratio of the propagation distance and the thickness remains constant,the ratio of SWPD at a certain propagation distance to the SWPD at the center point on the impact surface is sure to be constant.The method of numerical simulation is used to analyze the attenuation characteristics of the SWPD of the oxygen free copper target,and the quantitative analysis results verify the validity of the attenuation model.
