本文运用二维流体弹塑性模型,对自锻破片形成过程进行了数值计算,同时还使用脉冲x光高速摄影系统作了验证性实验.研究表明,计算得到的自锻破片形状和运动参数与实测结果基本符合.
In this paper, a two-dimensional fluid elastoplastic model was used to calculate the formation of self-forging fragments, and a confirmatory experiment was also carried out using a pulsed X-ray high-speed photography system. The results show that the calculated shape and movement parameters of self- The results are basically consistent.
