Abstract
In order to guarantee the new emission regulations and customer
requirements, crank train components must be developed for engine
operation boundary conditions. In the last years, analytical
formulation is being replaced by flexible dynamic analysis. This
paper shows how important it is to develop crankshafts considering
engine actual cyclic loads. Moreover, stresses and fatigue safety
factors are evaluated as vital outputs.
The consideration of the elastic matrix in the movement equation
enabled the achievement of more precise results according to the
actual crankshaft behavior. The procedure described in this paper
is strongly recommended for new crankshafts design regarding their
actual structural behavior under engine operation condition.
