Tolerance Analysis for the Assembly of Non-rigid Parts with Form Defects | Springer Nature Link
The tolerance model remains an open problem for research. Since real parts always have deviations from their nominal geometry due to many factors such as manufacturing inaccuracy, the designer must define and assign tolerances to limit deviations from the tolerance range. Since an ideal feature cannot express shape errors, most traditional assembly modeling methods and approaches do not consider shape defects, which can lead to an inadequate tolerancing decision. To effectively analyze the tolerancing of non-rigid assemblies, the influence coefficient method can then be used. The (MIC) method is simple and has proven advantages over the Direct Monte Carlo (DMC) method in terms of time cost. This paper aims to study the problem of non-ideal parts assembly by integrating the influence coefficient method (MIC) and using finite element analysis (FEA).
