Bolt Modeling Wizard in ANSYS

A Bolt Modeling Wizard, similar to the Contact Wizard, was developed to facilitate modeling of bolts. Ansys Parametric Design Language (APDL) scripts were used to model and mesh the bolts and Tcl/Tk was used to design a user-friendly Graphical User Interface (GUI). User Interface Design Language (UIDL) was used to interface this wizard with the "Preprocessor" menu of Ansys. The current version of this wizard models i) solid bolts with pretension, ii) bolts with BEAM4 for shank and rigid beams for head and nut iii) bolts with BEAM4 for shank and RBE3 command for head and nut and iv) bolts with BEAM4 for shank and shells for head and nut. Multiple generation of a solid bolt is implemented in this wizard. Solid bolts with pretension can be replicated in the cartesian and cylindrical coordinate systems. Six-sigma methodology was used to implement this wizard and the process capability with and without using the wizard was measured.
