Analysis of an Orbital Grinding System for Grinding

A crankshaft is the most critical component, and it can dominate the life of the engine. Nowadays an orbital grinding is widely used to grind a crankshaft. In this study, static analysis is done to find deformation of an orbital grinding system due to weight, modal analysis is done to obtain the natural frequencies, and harmonic analysis is done to investigate the compliance.

Engine Crankshaft: Crank Grinding

Most crankshafts are engineered to be about four times stronger than required, based on mathematical stress and load calculations, so a 4% reduction in fatigue life is virtually meaningless. Since torsional failures are almost nonexistent on gas engines, removing .040" from our 'torsion bar' is not a concern.
