1. A method of component monitoring for machinery having multiple rotating elements, which are rotated at different rotational speeds, and at least one vibration sensor, the method comprising:
- sampling data from the vibration sensor at a sampling rate sufficient to monitor a fastest rotational speed of the multiple rotating elements to form a data set;
determining an actual rotational frequency for at least some of the multiple rotating elements during the sampling of the data; and
generating a virtual vibration waveform from the data set for at least some of the multiple rotating elements by filtering the data set to a sampling rate to monitor each of the at least some of the multiple rotating elements.

Abstract
A method of component monitoring for machinery having multiple rotating elements, which are rotated at different rotational speeds, the method including sampling data from the vibration sensor at a sampling frequency at least as great as the fastest rotational speed of the multiple rotating elements to form a data set and determining an actual rotational frequency for at least some of the rotating elements during the sampling of the data.

11. An assembly, comprising:
-
rotating machinery having multiple rotating elements, which are rotated at different rotational speeds; a vibration sensor configured to measure vibrations of the multiple rotating elements; a tachometer configured to measure the rotational speed of one of the multiple rotating elements; and a processor operably coupled to the vibration sensor and tachometer to receive information therefrom and configured to sample data from the vibration sensor at a sampling rate sufficient to monitor a fastest rotational speed of the multiple rotating elements to form a data set, determine an actual rotational frequency for at least some of the multiple rotating elements during the sampling of the data and generate a virtual vibration waveform from the data set for at least some of the multiple rotating elements by filtering the data set to a sampling rate to monitor each of the at least some of the multiple rotating elements. - View Dependent Claims (12, 13, 14, 15)
