During the first stages of dimensioning of an engine, we must define major dimensions in particular those related to the crankshaft. The suitable choice of these coasts, dimensioning for other parts, requires several iterations. In such a situation, it is not easy to have resorts to structural finite-elements analysis which requires important means of calculation and lot of time.

Using a simplified model based on beam theory can be useful, fast and sufficiently accurate. The crankshaft is modeled by a cylindrical shaft, composed of four sections with elliptic cross-section. Each section represents a part between two bearings of the crankshaft of a four cylinders on line engine. This work presents a methodology of identification of the geometrical characteristics of the equivalent elliptic cross-sections which must behave like the real crankshaft.

Owning the CAD of the crankshaft of a four cylinder engine and the real loading along the combustion cycle we calculate with the finite element method the reactions in the crank journals. This methodology is simple and efficient to be used during quasi static calculations of the crankshaft.
