摘要
在恒定应力下加速寿命试验中,假定在各应力下产品的寿命分布为威布尔分布W(m,η),对于定数截尾样本,求分布参数和加速方程中系数的线性无偏估计(BLUE或GLUE)。在此基础上本文通过构造某些枢轴量,并用Mote Carlo方法给出了正常应力下产品可靠性特征量的置信区间。最后给出了一个数值例子。
In the constrained-stress accelerated life test. Under type H censoring of data from Weibuil distribution W(m,η), we give the lincar unbiased estimates (BLUE or CLUE) of the parameters for the distribution and the coefficients in acceleration equation. In this paper, we give some Pivot value and use the method Monte Carlo to give the confidence interval of some reliability characteristic under the usual stress, A numerical example is finally worked out for illustration.
