A calculation method is described of forced coupling bended-torsional-longitudinal oscillations of the automotive crankshaft. Frequencies of free amplitudes are defined by the method of rotation, amplitudes of forced oscillations are defined by the balance equation of delivered and dissipated energy. The oscillation interconnection can be defined by the deformation coupling, energy dissipation, influence of coupled masses and systems. Effect is shown of additional oscillation stresses on mechanical stress of crankshaft elements. Calculation results are compared with experimental results.
