Analyzing vibrations for better product quality
Analyzing vibrations plays a crucial role in measurement technology. By understanding and analyzing vibration phenomena, scientists and engineers can gain important information about the condition of machines, structures or systems. Vibrations can be measured and analyzed in various ways, e.g. by examining the frequency, amplitude or phase shift of the vibration. This analysis makes it possible to detect possible problems such as irregularities, defects or signs of wear at an early stage and to take suitable measures for optimization or maintenance. Vibration analyses are also of great importance in areas such as music, medical and environmental technology. Overall, they help to improve the efficiency, safety and performance of machinery and systems.
Vibrations are usually effects that disrupt the process and occur unintentionally. Vibrations damage machines and reduce efficiency and product quality. Vibration phenomena are perceived as noises, shaking, trembling or whistling, and it is often not easy to draw direct conclusions about the cause. The source of the vibrations must be found and eliminated.
The Expert Vibro device is ideally suited for this task. Thanks to the universal inputs, any sensor signals can be recorded. The signals are analyzed directly online with very high-resolution frequency spectra (FFT) or the calculation of characteristic values. Characteristic values contain relevant information on the energy content of vibrations. Regardless of when the vibration occurs - the self-sufficient Expert Vibro saves all data.
Application highlights for analyzing vibrations
- Detection of vibrations with any sensors
- Simultaneous acquisition of binary or analog process signals
- Analyzing the vibrations using frequency analysis
- Calculation of characteristic values such as vibration velocity
- Long-term recording for the detection of sporadic vibration phenomena
Practical example to analyze vibrations
Accurate pressure vibration measurement on a waste heat boiler
Vibrations occurred in a waste heat boiler downstream of a gas turbine, which led to noise in the form of sheet metal vibrations and disturbed the neighborhood of the power plant. Initially, it was not possible to find a clear cause. Only pressure vibration measurements that were carried out helped to locate the source in the boiler. After structural changes were made to the boiler, the measurement was repeated and the effectiveness was clearly demonstrated.
