What is Operational Modal Analysis for Trucks about?

This document discusses two applications of operational modal analysis (OMA) to trucks. The first applies OMA to vibration data from a truck tested on a four-shaker test rig to identify modal properties and validate a finite element model of the complete truck. The second applies OMA to engine run-up vibration data from a truck oil pan to identify how its modal properties change with operating conditions like temperature and oil level. OMA techniques like PolyMAX and stochastic subspace identification are u
