Bootstrap method was used to estimate small-scale sample test, whose samples exceed 10 in number. But for a large-scale complicated structure, the sample test consists of only 1 or 2 samples. We aim to provide an estimation method that can utilize Bootstrap method to estimate an extremely small-scale sample test. We provide a virtually expanded sample estimation method that can do so. If the shape of experimentally determined life distribution of similar samples and their standard deviation are known, the original 1 or 2 samples can be expanded to 13; the mean of 13 virtually expanded samples is kept the same as that of the original 1 or 2 samples; the standard deviation of 13 virtually expanded samples and that of similar samples are also kept the same. Based on these virtually expanded samples, the modified empirical cumulative distribution function can be built. At last, the inference about unknown parameter can be obtained by use of the Bootstrap method. An example is provided to show the application of the virtually expanded sample estimation method presented in this paper.

提出一种针对极小子样试验的虚拟增广样本评估方法。在工程实际中,对于成本昂贵的大型复杂结构体系或机构系统,往往只能做试件样本量为1或2的极小子样试验。在这种情况下,先根据极小子样试验的试验样本值虚拟增广样本,即把样本量从n=1虚拟增广至n=13,然后根据增广样本构造经验累积分布函数并对其进行修正,最后应用Bootstrap方法对增广样本进行评估,得到未知参数的估计。文中采用一个实例验证了所提出方法的实用性。
