The characteristics of crankshaft stresses were investigated by experiments and calculations for a 10 cylinder V-engine. The three-dimensional vibrations of the crankshaft system were calculated by the dynamic stiffness matrix method. The dynamic bending stresses at the front and rear fillets of the No. 1 crankpin in the crankthrow plane and torsional vibrations at the front pulley were measured. From the experimental and calculated results we found that : ( 1 ) The maximum bending stresses are caused by the bending vibrations coupled with torsional vibrations, and the peaks of the bending stresses always appear at the resonant engine speeds of the torsional vibrations. ( 2 ) The bending stress at the front fillet is strongly affected by the moments of inertia of the front pulley about the axis orthogonal to the No. 1 crankthrow plane, whereas the stress at the rear fillet is little affected by them.
