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.
The calculation of impact temperature is summarized into three kinds of approximate methods, and the three methods are summarized, and some methods for estimating material parameters are also given. When using the isentropic curve to calculate the impact temperature, a semi-analytical isentropic equation is derived from the impact insulation line. The impact temperature of iron was calculated and compared with the experimental measurements. The results show that the impact temperature calculated by using the equation of state equation and taking into account the influence of melting phase change potential is in good agreement with the measured value. In addition, several factors that affect the calculated impact temperature are also analyzed.
