Model of mating of parts with nominal coaxial surfaces of rotation

Proposed model allows determining the relative position of the mating parts on nominally coaxial surfaces of rotation. the model is based on the algorithm of the nearest points (icp),which simulates rigid contact of mat-ing surfaces. to determine the possible positions of the mating surfaces in the model assembly conditions are simulate,they are determined by the vector assembly force. uncertainties of mating pair of conical surfaces with the form deviation in the cross section are theoretically researched. conclusions about the significant in-fluence of the form deviation of the mating surfaces on the accuracy of the relative position of parts are ob-tained.
