..., such as tolerances and external mechanical loads, in the tolerancing process. The worst-case concept and the small displacement torsor (SDT) are used to model rigid parts with orientation and positional defects. To model the part with form defects, random positions of each toleranced face points are determined using...

...: the geometrical deviations modeling, the geometrical behavior modeling, and the tolerance analysis techniques. In this paper, a method is proposed to realize the tolerance analysis of an over-constrained mechanical assembly with form defects by considering the contacts nature (fixed, sliding, and floating...

... difference surface form defects gap hull non-interference The mechanical behavior of systems and products is primarily based on the geometric quality of parts and associated functional surfaces. Whenever there are relative movements of parts with mechanical loads, local pressure, and high...
