Vibration analysis method for determining the operating state of a machine, in which an instrumentation unit including sensor and data acquisition means are simply glued or tacked to the surface of the machine to be monitored

摘要

Operating data capture based on vibration analysis, whereby the actual state of a machine is determined from vibrations caused by it. A sensor is attached to the machine surface for vibration measurement. The vibration attributes, e.g. amplitude, bandwidth and cyclical behavior, are analyzed in order to determine machine operating state. A data transfer path, cable, optical fiber, radio or infrared, can be used to transfer the data to an evaluation computer for analysis.
