Abstract
A tolerancing method includes modeling positions and sizes of apertures in an assembly of parts. The parts are best-fit together. Aperture position in the parts is statistically varied. The best-fitting and statistical variations of the aperture positions are repeated for a statistically significant number of trials to create a statistical model. The size of fasteners for assembly through the mating apertures may be selected as determined in the statistical model.
Claims14
A method of tolerancing fasteners and apertures for assembling a plurality of parts having mating pluralities of said apertures receiving respective ones of said fasteners, comprising:
- modeling positions and sizes of said apertures in an assembly of said parts;
- best-fitting together said parts;
- statistically varying said aperture positions in said parts;
- repeating the best-fitting together of said parts and statistical variations of said aperture positions for a statistically significant number of trials to create a statistical model;
- and
- selecting size of said fasteners for assembly through said mating apertures as determined in said statistical model.
