A Selective Teager Huang Transform Technique for Bearing Fault Detection

ABSTRACT

Rolling element bearings are commonly used in rotary mechanical and electrical equipment. Online health condition monitoring plays a vital role in recognizing the bearing defect at its early stage so as to prevent machinery performance degradation and malfunction. According to investigation, more than half of the rotary machine faults are related to bearing defects. Although many signal processing techniques have been suggested in literature for bearing fault detection, reliable bearing fault diagnosis still remains a challenging task. One of the reasons is that bearing is not a simple component like a gear or a shaft, but a complex system; vibration signals generated from a faulty bearing are usually nonstationary, especially when there is a slippage. However, nonstationary signals are much difficult to analyze using classical signal processing techniques. The objective of this study is to develop an online condition monitoring system for bearing fault detection. In this work, a smart sensor-based data acquisition (DAQ) system is developed for vibration data collection, which consists of a sensing unit, a signal conditioning circuit and a wireless communication module. A selective Teager-Huang transform technique is proposed for bearing fault detection. The processing is undertaken in three steps: Firstly, a denoising filter is used to improve the signal to noise ratio; secondly, a correlation function method is suggested to choose intrinsic mode functions with most representative features related to the fault; and thirdly, a generalized Teager-Kaiser spectrum method is proposed to synthesize the extracted intrinsic mode functions for bearing fault detection. The bearing fault characteristic signatures can be identified from the energy spectrum. The accuracy of the developed smart sensor-based DAQ prototype is examined by comparison tests. The effectiveness of the proposed selective Teager-Huang transform technique is verified by experimental tests corresponding to different bearing conditions. Its robustness in bearing fault detection is examined by the use of the data sets from a different experimental setup.

Nanomaterials for Sustainable Energy via Green Chemistry


Abstract: Discovering how to efficiently convert solar energy into electrical/chemical energy is one of humanity's greatest challenges in the 21st century in view of the ever-growing global hunger for renewable energy solutions. Current research directives in solar energy conversion are investigating new methods, and, in particular, new materials and processes that will render integrated and more efficient power harvesters from solar energy. The solar to electricity or hydrogen conversion efficiency of many organic, hybrid organic-inorganic, and inorganic devices are still low. And the long-term stability of the devices cannot meet the requirements for commercialization. In this talk, I will focus on the synthesis of nanomaterials via wet chemistry approach and use the materials for fabricating of solar energy conversion devices, including liquid junction solar cells, luminescent solar concentration and solar-driven water splitting for hydrogen production. In the end, I will introduce the fabrication of water splitting devices using biomass, highlighting the use of natural resources for sustainable energy harvesting.

Lakehead Orillia and the Ontario Master Naturalist Program are participating in the Orillia Christmas Bird Count on Saturday, Dec. 14 and you’re invited to join our team, Lakehead Canada Jays!

Come and learn about local bird populations, how to identify birds in the wild, and be a part of citizen science. This is an outdoor event and will happen rain, snow or shine. We will be outside for most of the day so please dress for the weather and walking in snow.

If you would like to join the team, or if you have any questions, please contact Bob Bowles at masternaturalist@lakeheadu.ca.
