Abstract
Product quality in mechanical assemblies is determined by the dispersion of manufacturing variance during the structure building. This paper focuses on straight-build assembly and proposes a probabilistic approach based on connective assembly model to analyze the effect of individual component variations on the eccentricity of the straight-build assembly. The probabilistic approach calculates the pdf (probability density function) of key assembly variation of rotor assembly of high speed rotating machines. The probabilistic approach considers two straight-build scenarios: (i) Best Build; and (ii) Direct Build, for 2D (Two-Dimensional) "axi-symmetric" assemblies. Numerical examples are presented to investigate the probabilistic approach for its efficiency and accuracy in comparison to MCS (Monte Carlo simulation).
