摘要:将冲击温度的计算归纳为三种近似方法,并对这三种方法进行了概述,同时还给出了一些材料参数的估算方法.在利用等熵线计算冲击温度时,从冲击绝热线出发推导了一个半解析的等熵方程.计算了铁的冲击温度,并与实验测量值作了比较.结果表明,利用三项式物态方程并考虑熔化相变潜能的影响后算得的冲击温度与测量值符合得比较好,另外,本文还对影响冲击温度计算值的若干因素进行了分析.Abstract:In this paper,ways to calculate shock temperature are classified as three kinds of basic methods.These methods are described briefly and the evaluation of related material parameters is given also.In the calculation of shock temperature by using isentropic curve, an isentropic equation which is consistent with the Hugoniot curve is developed. Shock temperatures for iron are calculated and the results obtained by using three-term equation of state are in good agreement with the experimental results. In addit...
