My true passion lies in using finite element analysis (FEA) and other simulation programs to achieve graphical verification of theoretically based calculations. Working with the Solidworks Simulation finite element program on a daily basis, I perform stress and displacement analysis, modal analysis, dynamic analysis, fatigue analysis, and welded and bolted joint analysis on gears, gearbox housings, and other similar structures. Other simulation programs I routinely use include XLRotor for rotordynamics and calculation of critical speeds and mode shapes of shafts, Maple, and MapleSIM for dynamic analysis, and KiSSoft for bolted joints and gear ratings. I then write and communicate these...
