摘要：

The explosive compaction process of W-Cu powders was investigated by numerical simulation. The effect of detonation velocity on the density of the compact was studied. The spreading course of shock wave in powders and distortion rule of the powders were analyzed in the condition of 5000 m/s, and the mach reflection phenomena were also analyzed. The courses of loading and unloading were displayed by the displacement curves of side elements. The density of compacts was calculated by analyzing the curves. The results show that the density of compacts would arrive at a bigger value in the condition of 5300 m/s. The calculative results were applied to the experiment of explosive compaction, and the experiment results are consistent with the calculated.
