二维抛板极限速度的相似性与古尼公式的采用

A Similarity of the Limit Speed of Two-Dimensional Projected Plate and Adoption of the Gurney Formula

本文分析影响被炸药驱动下抛板极限速度的重要因素,讨论了一些经验公式的适用范围;提出了根据二维抛板的数值计算得到的两个重要规律:①在炸药与抛板的质量比相同的情况下,抛板的极限速度之间具有一定的相似关系;②修正的古尼公式可用来计算二维抛板的极限速度。

The important factors to affect the limit speed of a projected plate drivenby explosive are first analysed in this paper.This analysis is combined with adiscussion about the range of application of the empirical formulae.Then twoimportant laws,which are summarized from the results of the numericalcomputations to two-dimensional projected plate,are formulated:①Whenmass ratios of explosive and projected plate are the same,there is a certainlysimilar ralation among limit speeds of two-dimensional projected plate;②Therevised Gurney Formula may be used to calculate the limit speed of two-dimensional projected plate.
