前言从我们收集到国内外的气动凿岩机性能参数计算公式来看,都基本相似,甚至修正系数的取值范围也都非常接近。我们认为这套公式可作为设计气动凿岩机时,进行性能参数计算的重要公式来应用。但这套公式经一系列的数学推导、变换得比较简单,应用的关键是如何正确选择公式中修正系数的具体问题。为了能合理地选取修正系数值,以便能较精确地计算气动凿岩机的性能参数,本人以多年来收集的
Foreword From our collection of domestic and international calculation formula of pneumatic rock drill performance parameters, are basically similar, and even the range of correction coefficients are also very close. We think this formula can be used as an important formula for calculating the performance parameters when designing a pneumatic rock drill. However, this formula is derived from a series of mathematical deductions, and the transformation is relatively simple. The key point of the application is how to correctly select the specific problem of the correction coefficient in the formula. In order to reasonably choose the value of the correction factor in order to be able to more accurately calculate the performance parameters of pneumatic rock drill I have collected over the years
