| Abstract: | Three-node and quadratic Timoshenko beam element is employed to model the engine crankshaft, which includes the effects of transverse shear and accounts for the initial curvature of the beams. The free vibration modes of an inline four-cylinder crankshaft are analyzed and the results are compared with those determined analytically and experimentally values available in the open literature. Subsequently, the operating crankshaft is simulated in three-dimensional and the dynamic response is calculated and analyzed. |
