Embodiment Construction

[0017] discussed below Figure 1 to Figure 7B , and the various embodiments used to describe the principles of the invention in this patent document are by way of illustration only and should not be construed in any way as limiting the scope of the invention. Those skilled in the art will understand that the principles of the invention may be implemented in any type of suitably arranged device or system.

[0018] figure 1 An example vibration severity analysis system 100 according to the present disclosure is illustrated. like figure 1 As shown in , system 100 includes a vibration severity analyzer 102 that analyzes physical vibrations generated by one or more machines 104 during their operation. For example, analyzer 102 may receive signals from one or more vibration transducers 106 physically coupled to or otherwise associated with machine 104 . Analyzer 102 analyzes the received signals to determine the health or operating status of machine 104 . The analyzer 102 may g...

Abstract

A method includes obtaining (602) a baseline vibration level of a machine (104), and normalizing (604) the baseline vibration level by a prescribed threshold (108) to generate a normalized baseline vibration level. The stated threshold is based on the type of machine. The method also includes obtaining a measurement of the operating vibration level of the machine during its operation, normalizing (616) the measured operating vibration level against a normalized baseline vibration level, and identifying (624) at least the An indicator of the status of the machine.

Description

technical field [0001] The present disclosure generally relates to control systems. More particularly, the present disclosure relates to a vibration severity analysis device and method for rotating machinery. Background technique [0002] A machine that performs some type of physical work typically generates physical vibrations as a function of its operation. For example, electric motors may generate vibrations due to minor levels of imbalance in the electric motor's shaft, misalignment of the electric motor's shaft relative to its load, or excessive bearing play caused by wear. It is even possible to generate a radial variation of the armature of the motor relative to the field winding of the motor. In many cases, it is desirable for a motor or other rotating machine to generate a certain level of vibration during its normal operation. However, it is subject to increased vibration levels for various reasons, such as failure or wear of one or more of its components due to...
