为了提高自动扶梯部件防滑等级划分的可信度,将显著性检验方法应用其中。根据可接受角度均值对部件进行等级预划分,再结合方差采用显著性检验的数学方法对结论的可信度进行估计;若可信度不能满足要求,则增加试验次数,并重复等级划分及验证可信度的步骤,直至其准确度较高或试验次数足够大。实例验证表明,该方法提高了防滑等级划分的可信度,又保证了试验效率。
In order to improve the credibility of the classification of escalator parts non-slip grade, the significance test method is applied. According to the acceptable angle of the average value of the components of the pre-classification, combined with the variance of significant test mathematical method to estimate the credibility of conclusions; if the credibility can not meet the requirements, increase the number of trials, and repeat the classification and verification The credibility of the steps, until its high accuracy or number of trials large enough. The example verification shows that this method improves the credibility of the classification of non-slip grades and guarantees the test efficiency.
