An in-service dynamic model of a diesel railcar from operational modal analysis and finite-element model updating

Last updated on 12 September 2014 2:01

Builders of passenger rail vehicles need methods for predicting vibrational behaviour so that they can meet ride quality specifications. Conventional finite-element (FE) models used for stress analysis may not be accurate enough for this because of imponderables such as the stiffness of spot-welded joints. One solution is to adjust FE...
