A vibration analysis method includes the steps of: inputting data about damage of a rolling bearing (S10); calculating, by a dynamics analysis program, a history of a displacement between inner and outer rings occurring to the rolling bearing due to the damage when a rotational shaft of the rolling bearing rotates (S40); calculating a vibration characteristics model of the bearing device by a mode analysis program (S60); and calculating a vibration waveform at a predetermined position on the bearing device by applying, to the vibration characteristics model, a history of an exciting force obtained by multiplying the displacement between the inner and outer rings calculated in the step of calculating a history (S40), by a bearing spring constant (S80). |
