... for modeling; modal analysis methods (Samper and Formosa, 2007) control shape defect tolerances, but these methods require an infinite number of points to describe geometric deviations introduced by the manufacturing process and assembly. To address this issue, skin model shapes have been proposed to represent...

.... 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 nonideal planar mating surfaces, and the progressive contact method...

...Ting Liu; Yan-Long Cao; Qijian Zhao; Jiangxin Yang; Lujun Cui Purpose The purpose of this paper is to carry out an assembly tolerance analysis by means of a combined Jacobian model and skin model shape. The former is based on small displacements modeling of points using 6 × 6 transformation...
