摘要
爆压对炸药爆轰合成超微金刚石的得率有很大影响
而实验过程中很难对它进行准确地观察和测量.本文用有限元动力学程序模拟爆轰产物的膨胀过程
得到炸药整个爆轰及膨胀过程中压力p随时间t的变化历程
对各种装药条件、约束条件、保护条件、起爆方式做了模拟
对计算结果与实验结果进行了比较
结果表明两者是一致的.
Abstract
The pressure has obvious effect on the yield of the synthesis of ultrafine diamond by explosive detonation
but it is to hard to accurate observing and measuring it in the experiment process. The process of expansion of the detonation products is simulated using finite element code in this paper. The pressure of detonation at different times in the expansion process are obtained. Different charge conditions
constraint conditions
protective conditions and initiation systems are simulated. The computation results are compared with the experiment results
