Experimental Modal Analysis to Represent Structural Components in Vehicle Models 2001-01-1403

This article describes a technique being developed to determine representative models of difficult-to-analyse structural components such as the fully-trimmed car body directly from measured Frequency Response Functions.
Details are provided of a new system identification method called the Global Smoothing Technique which is proving to be relatively reliable and robust even when the modes exhibited by the structural system tend to be highly-damped, closely-coupled and complex.
