PROBLEM TO BE SOLVED: To create a CAE model for vibration analysis of a drive shaft assy in a rotating state around an axial line and attain easy and highly precise creation of the CAE model. SOLUTION: The torque working in the rotational direction and break angle direction at an arbitrary position on a drive shaft 1 is modeled as the CAE model for vibration analysis of the drive shaft assy. In the torque model, spring constants and attenuation coefficient are determined, based on test results of an oscillating test with the drive shaft assy rotated around the axial line, therefore, correspond to those of the case when the drive shaft assy is rotating; consequently the CAE model as well corresponds to the case when the drive shaft assy is rotating.
