The probability distribution is graphically represented at the tab-page ‘Distribution’. By simply using the -button, it is possible to make comparisons of interest between the statistical results for different mechanical components in a system. As shown in the picture, the probability distribution of basic reference life for the different bearings mounted on the same shaft are compared with each other. The maxima of the curves are close to each other, but the variance for the roller bearing ‘B2’ is much larger. These analyses are useful to help identify restrictions or weaknesses in the design.
