Tolerance analysis of planar parts with skin modeling considering spatial distribution characteristics of surface morphology and local surface deformations
Abstract:Purpose
This paper aims to develop a method to improve the accuracy of tolerance analysis considering the spatial distribution characteristics of part surface morphology (SDCPSM) and local surface deformations (LSD) of planar mating surfaces during the assembly process.
Design/methodology/approach
First, this paper proposes a skin modeling method considering SDCPSM based on Non-Gaussian random field. Second, based on the skin model shapes, an improved boundary element method is adopted to solve LSD of nonide… Show more
