The Relation of the Geometric Parameters to the Maximal Principal Stress of Crankshaft
he transition fillet regions linking the bell crank and the crank-arm and linking the crankarm and the bearing journal are the regions where the strength is the weakest in crankshaft. Based on a crank-shaft model, the effect of the geometric parameters on maximal principal stress at the two transition fillet regions was analyzed using FEM and software ANSYS8.0. It was concluded that the maximal principal stress at the two transition fillet regions is related not only to the transition fillet radius but also to the bell crank length and the crank-arm width.
