Many readers probably think “black magic” describes the math involved in finding the dynamic response of a structure from random excitation. When can you be sure you have jumped through all the ...

There's typically no way around it. At some time during a motor's life, it is likely to experience high vibration levels. What's behind this maintenance phenomenon? The cause may be an electromagnetic ...

Part 1 of this series addressed the advantages and disadvantages of various vibration sensors; Part 2 examined signal conditioning and system hardware selection and configuration. I’ll wrap up by ...

Vibration analysis is a powerful and non-invasive way to measure, understand, and quantify the internal dynamics of mechanical systems, but the cost of the necessary instrumentation is sometimes a ...
