Practical application of random vibration signal analysis on structural dynamics

The use of random signal analysis in vibration and structural analysis is discussed and documented. The need to minimize product performance and durability risks due to competitive pressure in the marketplace has forced industry to streamline methods of product design, processing, and evaluation. Engineers need to be experienced in much more advanced techniques than they did even a decade ago. Random vibration signals are used to simulate real world environments and are another tool in structural analysis. This investigation outlines the basics of random vibrations, frequency analyzers, data analysis, along with associated noise and errors problems. A case study using an aluminum beam is used to demonstrate the concepts presented in this work
