金属低温冲击试验吸收能量的概率分布

摘要

应用数理统计理论,将钢材冲击试验吸收能量视为随机变量,分别基于两种钢材的30个低温冲击试验同质性吸收能量数据,分析了吸收能量的概率分布.%Based on the theory of mathematical statistics, the energy absorbed by steel impact test is regarded as a random variable. Based on the homogenized energy absorption data of 30 low temperature impact tests of two steel materials, the probability distribution of absorbed energy is analyzed.
