目前,我国地下铲运机还没有形成系列,在设计新的地下铲运机时,极需一些简单而又实用的经验公式作为初步设计时的概略计算,为确定整机的总体参数提供一定依据。本文以一元回归分析法(即最小二乘法)为工具,对目前国外广泛用于一般金属矿山的液力机械传动的地下铲运机,共二十多种机型的总体参数进行分析归纳,从而得出十个经验公式。并以相对误差的标准σ,给出了这些公式的误差估计。本文还就使用这些公式时需要注意的问题作了必要的说明。
At present, China has not yet formed a series of underground scraper, in the design of a new scraper, it is necessary to some simple and practical empirical formula as a preliminary design of the rough calculation, to determine the overall parameters of the machine to provide a basis . In this paper, a univariate regression analysis (ie, least-squares method) is used as a tool to analyze and summarize the total parameters of more than 20 kinds of models currently used abroad for hydraulic scrapers, which are widely used in general metal mines. Draw ten empirical formulas. The error estimates of these formulas are given by the standard error σ. This article also makes the necessary explanations on the issues that need attention when using these formulas.
