摘要
采用二维有限差分非线性动力数值计算程序（Ａｕｔｏｄｙｎ－２Ｄ）对高速钢球侵彻水介质时瞬时空腔的形成及其发展过程进行了数值模拟，获得了钢球侵彻水介质过程中速度衰减的规律、水介质中速度场和压力场的分布等数值模拟结果。数值模拟的结果与实验结果及现象相符。数值模拟结果及其相关分析为从理论上深入分析研究高速投射物对生物的致伤机理提供了重要的依据。
By using the two dimensional finite difference non linear dynamics program Autodyn 2D,we simulate and analyze that the temporary cavity forms and develops during the high velocity steel ball penetrating into water and obtain that the damping rule of steel ball velocity and distribution of the velocity field and pressure contours in water.The numerical simulation result is in good accord with the experimental result.It provides important basis for the further research and analysis of the wound mechanism that the high velocity projects wound the living tissue and organ in theory.
