To analyze the three-dimensional vibration behavior of the crankshaft system, the crankshaft was idealized by a set of rigidly jointed structure consisting of rods and beams, the pulley and the flywheel by a set of lumped masses and moments of inertia, and the journal bearings by a set of springs and dashpots. The dynamic stiffness matrix for the complete crankshaft system was derived from the principle of superposition and the natural frequencies were calculated from compliance matrix. These modeling and calculation methods were applied to the analysis of two kinds of planar structure crankshafts, one for a single cylinder engine, and the other to a four-cylinder in-line engine; the calculated natural frequencies and mode shapes coincided well with the experimental results.
