A coarse-mesh finite element model of an engine cradle structure is experimentally correlated using the structural system identification technique. The coarsemesh model represents the cradle structure with beam and spring elements. The structural system identifcation code SSID is used to update the structural properties to correlate the model with measured(More)
Design and development decisions are often based on the predicted and/or measured values of the frequenck?s of the vibration modes of a vehicle. It is known that test variability can affect our ability to experimentally measure these frequencies. Consequently, it is important fo understand and quantify typical fesf-fo-test variations. One method to isolate(More)
