For a simple description of crankshaft vibration behavior the crankshaft was idealized by a set of jointed structures consisting of round bars and beam blocks. The front pulley, crank gear, and the flywheel were idealized by a set of masses and moments of inertia, or by a simple FEM model. The main journal bearings were idealized by a set of linear springs and dash-pot systems. The dynamic stiffness matrix for the total system was constructed using the principle of superposition, after derivation of the dynamic stiffness matrix for each constituent member. This modeling and analysis were applied to analysis of free vibrations and forced vibrations under firing conditions of automobile engine crankshafts.
