摘要
研究了矿用钢丝绳的使用寿命问题。用柯尔莫哥洛夫检验法检验寿命数据是否服从正态分布及对数正态分布,用最小二乘法(MIS)检验是否服从Weibull分布,并对Weibull分布的三参数进行估计,给出了三参数的置信区间及钢丝绳使用过程的可靠度。
The problems of replacement lifetime of wire ropes used in mining are studied in this paper. Lifetime data are tested. Normal distribution and Logrithm distribution are tested by kolmogoroff test, Three parameters of weibull distribution are estimated by the method of least squares. The confidenee intervals of three parameters and reliability of wire rope in using process are given
