This study covers the analysis of the heat can be generated by mechanical vibrations. Vibrations are an essential indicator in the industry, which evaluate and monitor the condition of the machines. In practice, when a machine vibrates under higher frequencies causes higher displacement, noise, and heat generation. Infrared thermography is among th...

In this study we present an evaluation of the energy consumption in the case of shaft misalignment. Misalignment is one of the most common defects in rotating machinery that causes noticeable losses of energy. The proposed methodology focuses on finding a correlation between vibration level and energy consumption for different degrees of misalignme...

Unbalance is one of the most common defects in rotating machinery that causes important vibrations and subsequently an increase in energy consumption. Unbalance is defined as un-equal distribution of weight around the center of rotation. Although vibration, heat and noise are usually the results of mechanical defects, vibrations present the most re...

Vibration analysis is a key element of predictive maintenance of rotating machines. Several signal analysis methods are used to obtain useful information from vibration signatures. This signal highlights the changes in time domain (root mean square), in the frequency spectrum (Fourier Transform) and in the time-frequency (Short Time Fourier Transfo...

A predictive maintenance is a philosophy or attitude that uses the actual operating condition of plant equipment and systems to improve overall effectiveness of manufacturing and production plants. a predictive maintenance program based on vibration analysis deals with potential vibration problems by using electronic hardware and software to monito...

Vibration monitoring of rolling element bearings is probably the most established diagnostic technique for rotating machinery. The application of ultrasound technique for bearing diagnosis is gaining ground as a complementary diagnostic tool. In fact, many similarities exist between these two methods and their principle is to not so far. The experi...

Bearing wear is one of the main causes of failure of rotating machinery. Vibration analysis is the most widely used detection method for the monitoring and diagnosis of bearings. However, it cannot provide all the information required for the implementation of a preventive maintenance program. Therefore, a comprehensive preventive maintenance progr...
