This report refers in detail to the numerical calculation of the analysis mentioned in the first report, and also investigates the adequacy of the vibration model adopted in the analysis, by comparing the results of the calculation with the experimental data of forced torsional vibration in a 141, V8 engine.<BR>As a result of the comparison, the authors wish to emphasize that forced torsional vibration can be calculated with adequate accuracy by adopting this present method, provided that the correct input data is specified.<BR>The calculation capacity of this program is approximately 200 KB. Each throw of the crankshaft is virtually divided into 18 elements. It took approximately 3 seconds by HITAC 8800/8700 computer system to calculate displacements, angular displacements, forces, moments and stresses in the x, y and z directions at each divided point per engine speed and per order.
