[0084] Before using the system 10 to collect vibration data, the preferred embodiment implements a determination to configure a vibration data collector

[0089] Referring to Figure 2, the next step is to determine the minimum frequency separation (Δf) between all fault frequencies, rather than two

Abstract

The present invention provides a computer-implemented method for determining the maximum frequency (F max ) and linear resolution (N lines ) in order to sufficiently distinguish the spectral peaks used to identify machine bearing faults. The method can be extended to any other types of fault frequencies that a machine may have, such as motor fault frequencies, pump / fan fault frequencies, and gear mesh fault frequencies. Embodiments of the method also ensure optimization of the time required to acquire the waveform. This is especially useful when collecting data using portable vibration monitoring devices.

Description

Waveform acquisition optimization technical field [0001] The present invention relates to the field of machine vibration data analysis. More specifically, the present invention relates to a method for optimizing machine vibration A system for the collection of dynamic data to enhance spectral waveform analysis. Background technique When acquiring machine vibration data for spectrum analysis, it is necessary to The resolution collects data to adequately discriminate between various spectral amplitude peaks, enabling identification of potential mechanical faults associated peaks. This requires a vibration monitoring device (such as the Emerson Model AMS2140 Mechanical Health Analysis) that collects data in the configuration instrument) when defining the correct maximum frequency (F max ) and the correct line count resolution (N lines ). Therefore, there is a need for a method for determining F max value and N lines method for the value used to confi...
