The vibration stresses of crankshafts in the reciprocating combustion engines have become severer with increase of their power and speed. It has become much more important to estimate all the vibration stresses accurately in the design stage of a crankshaft.<BR>The first report described the three dimensional analysis of forced vibrations of the crankshaft by the transfer matrix method in detail. This analysis program can calculate axial, bending, and torsional vibrations of a crankshaft.<BR>The second report referred to the numerical calculation by the analysis program, and it was found that the estimated torsional vibration stresses are in approximate agreement with the measured ones under forced torsional vibration.<BR>In this report, it is described that the measured bending stresses of the crankshafts are compared with the calculated ones and that they are in good accordance. And it is found that the coupled bending stresses caused by torsional vibration can be estimated in a certain degree of approximation by this analysis program.
