| Abstract: | The influence of external fits on the probability distribution of internal fits in assembly is discussed. Two cases of external fits, the interference and the transition ones, are investigated. The mathematical model and accurate method for calculating the probability distribution of the internal fits are given with the influence of assembly deformation due to external fits taken into account. The calculation results show that, with a decrease of interference probability P1 of the external fit from 1 to 0 , the deviation of the internal fit probability density function from the normol distribution increases first but then decreases. The maximum deviation occurs at P1= 0.6 in an example given in this paper. |
