Detection of Gear fault using vibration analysis

The new generation of condition monitoring and diagnostics systems differs by the detailed solution of diagnostic problems that allows making a step from machine vibration state monitoring to the monitoring of the machine technical condition. Most rotating machine defects can be detected by such a system much before dangerous situations occur. It allows the efficient use of stationary on-line c...

Statistical modeling of gear vibration signals and its application to detecting and diagnosing gear faults

A statistical model of gear mesh vibration signals is proposed in this paper. It is seen that the sample mean is first removed from the gear mesh vibration signal, and the remaining signal components are approximated with a set of sinusoidal functions in the signal model. The signal model parameters can be estimated by the least-square method and the optimal model order is determined based on t...

Fault Detection using DPCA-based Control Charts

In this paper, Hotelling’s 2 T chart and the DPCA(Dynamic PCA)-based 2 A T and Q charts are applied to real oil data histories obtained from condition monitoring of heavy hauler truck transmissions. The objective is to evaluate the impending failure detection capability and the false alarm rate of the control charts in a CBM (conditionbased maintenance) application. When applied to failure hist...

Bearing Fault Diagnosis Based on Vibration Signals

The vibration signal obtained from operating machines contains information relating to machine condition as well as noise. Further processing of the signal is necessary to elicit information particularly relevant to bearing faults. Many techniques have been employed to process the vibration signals in bearing faults detection and diagnosis. Two common techniques, time domain techniques and freq...

Understanding Vibration Spectra of Planetary Gear Systems for Fault Detection

This paper explores the vibration spectra for planetary gear systems by studying a kinematic model of vibration and comparing the model with measurements of two helicopter transmissions made in flight. The model and flight data include systems with both uniformly and nonuniformly spaced planet gears. This model predicts vibration to occur only at frequencies that are integer multiples of the pl...
