Application of the Pearson's distributions for characterizing the surface roughness of machine components
Journal Title: Tribologia - Year 2010, Vol 234, Issue 6
Abstract
The family of the Pearson’s distributions of probability has been presented. These distributions have been defined as the functions of the asymmetry and concentration of the random variable, i.e. the dimensionless skewness parameter Sk and the dimensionless kurtosis parameter Ku. The probability distributions of the seven Pearson’s distributions have been given. The connecting point of these distributions is a normal one. The results of the measurements of the surface roughness of a number of the unworn and worn machine elements have been presented, for which the Pearson’s analysis has been applied.<br/><br/>
