Rotating bearing analysis and monitoring system

A computer program product for analyzing vibrations of a bearing installed in a rotating machine comprising:

• a computer usable medium having computer readable program code means embodied in said medium for accessing vibration data corresponding to the bearing to be analyzed;
• computer readable program code means for determining a degraded condition factor BD for the bearing from the vibration data;
• computer readable program code means for selecting an expected designer-determined mean-time-to-failure MTTF of the bearing operating under a design load in the operating environment of the rotating machine;
• computer readable program code means for selecting a forecast time period;
• computer readable program code means for calculating a reduced mean-time-to-failure RMTTF of the bearing using the expected designer-determined mean-time-to-failure MTTF and the degraded condition factor BD;
• computer readable program code means for calculating a probability of failure of the bearing in the forecast time period using the reduced mean time to failure RMTTF;
• computer readable program code means for accessing cost data corresponding to a cost of failure of the bearing in the rotating machine;
• computer readable program code means for calculating a financial risk from the calculated probability of failure in the forecast time period and the cost data;
• and
• computer readable program code means for displaying the financial risk for the selected time period.
