套管内金属管爆炸挤压运动的一维不可压流体模型

本文采用一维不可压流体动力模型，考虑爆炸产物轴向飞散引起的稀疏波的影响，求解金属管在套管内的爆炸挤压运动，计算结果与实测相当一致，表明该模型在管挤压运动直至中期阶段是有效的。

A KINETIC MODEL FOR ONE DIMENSIONAL INCOMPRESSIVE FLUID EXTRUDING ON A STEEL PIPE UNDER EXPLOSIVE PRESSURE ENHANCED WITH AN OUTER PIPE

In view of the effect of released wave resulting from axial extension of explosive substance, this paper, by the use of the one dimensional incompressive fluid kinetic model, solves the inward extruding motion of a finite long steel pipe under explosive pressure enhanced with an outer pipe. The fact that the result from calculation conforms with the result of experiment shows that the use of this model is adequate in the analysis of the motion of the steel pipe at least from the beginning to the middle stage.
