摘要:

探讨了惰性块式平面波发生器的相关原理,在费马原理的基础上设计了平面波发生器的物理模型,用非线性有限元方法对平面波形成过程进行了数值模拟,得到了不同时刻的波形图像,数值模拟结果与实际过程在物理宏观特征上基本一致。

Abstract:

The principle of Inert Material Type Plane Wave Generator is discussed in this paper. A physical model of Plane Wave Generator to form planar shock waves is designed based on Fermat theory. The explosives detonation is calculated numerically with the nonlinear finite element hydrodynamics algorithm. The images of shock waves at the different time are obtained. The physics character is obtained from simulation analysis accords with the really process.
