Application of Modal Analysis and Operating Deflection Shapes on the Study of Trucks and Buses Dynamic Behavior

The application of modal analysis and operating deflection shapes (ODSs) in the study of structural vibration problems has been known for years. But these tools are also very useful in the study of vehicle dynamic behavior.

This paper presents applications of these experimental techniques on the study of the dynamic response of trucks and buses. It also discusses the relationship between modal analysis and operating deflection shape measurements.
