Vibration Fault Diagnostics for Quality Control and Component Reuse

The book "Vibration Fault Diagnostics for Quality Control and Component Reuse" offers a comprehensive analysis and innovative approaches to improving the quality control of household appliances through automated vibration detection. It addresses the diagnostics and prognosis of mechanical failures in electric motors and washing machines, focusing on the preprocessing of raw data to reduce measurement noise. The authors present new algorithms for noise suppression that enhance the detectability of mechanical faults by improving spectral analyses. Practical examples and the combination of classical methods with modern approaches, such as wavelet transformation, are explained in detail. Additionally, insights from accelerated lifetime tests are presented, showcasing the potential for the reuse of motors and gears. The methods introduced are designed to be integrated into existing lifetime estimation methods.
