摘要: 采用柯尔莫哥洛夫-斯米尔诺夫检验法(K-S检验法),对10CrNi3MoV钢埋弧焊接头的冲击功(Akv)的概率分布进行了研究。结果表明,Akv的概率统计分布为正态分布,对应可靠度为0.9,0.975和0.99时的安全冲击功为77.4 J,68.8 J和64.1 J。Abstract: The probability distribution of impact energy (Akv) for 10CrNi3MoV steel welded was studied by use of Kolmogorov-Smirnov test. The result showed probability destribution of Akv is the normal distribution and safe impact energy at reliability 0.9,0.975 and 0.99 is 77.4 J,68.8 J and 64.1 J,respectively.
