BEARING DEVICE VIBRATION ANALYSIS METHOD, BEARING DEVICE VIBRATION ANALYSIS DEVICE, AND ROLLING BEARING STATUS MONITORING DEVICE |
摘要 |
A vibration analysis method includes the steps of: inputting damage data of a rolling bearing (S10); calculating, by a dynamics analysis program, a history of an exciting force occurring to the rolling bearing due to damage when a rotational shaft of the rolling bearing is rotated (S40); calculating, by a mode analysis program, a vibration characteristics model of the bearing device (S60); and calculating a vibration waveform at a predetermined position on the bearing device by applying to the vibration characteristics model the history of the exciting force calculated in the step (S40) of calculating a history of an exciting force (S80). |
