First Claim
Patent Images
1. A method, comprising:
- determining, using at least one processor, a health indicator at a given time and a rate of change of the health indicator over a period of time for a component of a system including one or more components, the health indicator having been determined based on vibration data associated with the component; and
determining, using at least one processor, a future time for the component as a function of the health indicator and a material constant, the material constant being determinable as a function of the rate of change of the health indicator, the component being subjectable to fatigue from the given time to the future time, wherein determining the future time includes determining a number of fatigue cycles.

Abstract
A method, apparatus and computer program product are provided for determining a future time associated with a component, where the future time can be indicative that some action can be taken with respect to the component. In some embodiments, the future time can be indicative of a component'"'"'s remaining useful life or time until maintenance is required. The future time can be determined as a function of a health indicator and a material constant. In some embodiments, the functional relationship between the future time, the health indicator and the material constant can be based on the functional relationship of Paris'"'"' law for fatigue crack growth.
