Analysis of machine components based on geometric dimensioning and tolerancing (GD and T) of positional and perpendicularity values using finite element method
Analysis of machine components based on geometric dimensioning and tolerancing (GD&T) of positional and perpendicularity values using finite element method
Abstract:
This research conducted three-dimensional modeling of two machine components: the main body, which was specified with geometric dimensioning and tolerancing (GD&T) regarding positional accuracy, and the cover lid of the main body, which was specified with GD&T regarding perpendicularity, following the ASME 14.5-2018 standard. The theoretical assembly of machine components with GD&T involves geometric tolerances affecting assembly accuracy and efficiency. The impact resulting from specified GD&T tolerances was analyzed by categorizing assemblies into nine sample groups. Subsequently, Finite Element Analysis (FEA) was employed to analyze the assemblies, and the results were summarized to investigate the impact on the assembly process. Furthermore, potential issues arising from the specified GD&T values of the machine components were presented for further consideration
