Outline of Machinery Fault Diagnosis MethodIJRES Journal
Traditional mechanical equipment fault diagnosis methods are simple, and research is relatively simple, but it can not meet the demand of modern machinery development. Thus a large number of new methods are popular about modern machinery and equipment fault diagnosis. With the development of science and technology, the methods of modern machinery and equipment fault diagnosis become more and more complex. Therefore, it is necessary primarily focus on modern machinery fault diagnosis method, in order to facilitate the researchers access to use.

Induction Motors Faults Detection Based on Instantaneous Power Spectrum Analy...IDES Editor
A method of induction motor diagnostics based on
the analysis of three-phase instantaneous power spectra has
been offered. Its implementation requires recalculation of
induction motor voltages, aiming at exclusion from induction
motor instantaneous three-phase power signal the component
caused by supply mains dissymmetry and unsinusoidality. The
recalculation is made according to the motor known
electromagnetic parameters, taking into account the
electromotive force induced in stator winding by rotor currents.
The results of instantaneous power parameters computation
proved efficiency of this method in case of supply mains voltage
dissymmetry up to 20%. The offered method has been tested
by experiments. Its applicability for detection of several stator
and rotor winding defects appeared in motor simultaneously
has been proved. This method also makes it possible to
estimate the extent of defects development according to the
size of amplitudes of corresponding harmonics in the spectrum
of total three phase power signal.
FAULT DETECTION AND DIAGNOSIS OF INDUCTION MACHINE WITH ON-LINE PARAMETER PR...Sheikh R Manihar Ahmed
Today all instrumentation system pertaining to industrial process controls as well as domestic application involve automatic fault finding facility. This facility detects the faulty condition of the system and draws operator’s attention towards it enabling him to take suitable remedial action to ensure proper operation of the system. The main purpose of all FDI method is to monitor the system operations and in case of faults accommodate the source of faults so that timely corrective actions are taken. Fault detection simply involves a decision based on the monitored data as to whether there is a fault or the system is running normally. Fault isolation is then executed to identify the type and location of a fault after the fault detection has triggered an alarm so that corrective actions can be made. These two steps are known as Fault Detection and Isolation. Fault diagnosis is referred to as the combination of fault detection, identification and isolation. One such method of annunciation in which activation of visual or mechanical variable takes place when a removed switch or device has been activated as a result of fault in certain system, an audio alarm may also be associated with annunciations. This FDI system is defined and the existing technique to detect & isolate the fault with on-line parameter programming facility. The main advantage of the proposed approach of Control System based fault detection and isolation is its low cost. Low cost in terms of components used makes affordable in terms of easy handling and maintenance and various sensors can be used to give different types of input signals to circuit. An additional advantage is that the real time system still works when the host crashes, the matter that increases the reliability of the system & Data-logging facility can also be provided. A data-logger captures any measurement values which can be represented by a voltage. Nowadays, sensors and transducers are available for, practically, any physical quantity. The function of data-logger is to capture and store a specified number of specified number of sensor measurement values at predefined intervals and transfer the data including date and time to a PC in the form of file.
Induction motor fault diagnosis by motor current signature analysis and neura...Editor Jacotech
This paper presents steps in designing dimensions of antenna and feed in axisymmetrical Cassegrain Antennas. Corrugated conical horns are used as feeds in applications with circular polarization. In the initial design steps, diameter of the main reflector is determined considering communication link budget, then feed dimensions are designed to create optimum aperture efficiency. In the last step of design, considering feed dimensions and the amount of its center phase displacements with respect to its aperture plane, dimensions of subreflector is determined to avoid additional blockage. To illustrate the procedure, an applicative design example is presented in X-band.
SIGNAL PROCESSING TECHNIQUES USED FOR GEAR FAULT DIAGNOSISJungho Park
The slides are about signal processing techniques widely used for gear fault diagnosis (also the techniques could be used for other various rotating machine diagnosis such as bearing, rotor, motor, etc.). The techniques include wavelet transform, EMD (empirical mode decomposition), HHT (Hilbert-Huang transform), AR-MED filter, Spectral kurtosis, and cyclo-stationary analysis.
Diagnostic agents-used to detect impaired function of the body organs OR to detect abnormalities in tissue structure
a) Water soluble contrast media
eg. phosphate or citrate buffer
b) Water insoluble contrast media
eg. Propyliodone, Iopanoic acid.
To test kidney function eg. Indigotindisulphonate (Indigo carmine)
b) To test liver function eg. Sulphobromophthalein Sodium.
c) Miscellaneous eg. Florescein Sodium, Evens blue, Congo red.
