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.
