First Claim
Patent Images
1. A machine health monitoring method, comprising:
- receiving vibration data indicating vibration of a machine or a component of the machine;
determining damage to the machine or the component for each of a plurality of load cycles based on the vibration data;
determining the time rate of change of the damage to the machine or the component over the plurality of load cycles; and
determining a damage rate based on the time rate of change of the damage to the machine or the component relative to a baseline damage rate.
