Fe Model Adjustment of a Composite Material Car-Body By Means of Experimental Modal Analysis on the Prototype 91A095
A procedure adopted to verify and update the finite elements
model of an electric powered car-body manufactured from composite
materials is described.
Experimental results, obtained from modal testing of the
prototype, are used in order to identify and correct discrepancies
in the FE model. The availability of a highly reliable FE model
allows to simulate structural modifications by computer, optimizing
the use of composites and reducing in the same time at minimum
prototypes construction. The approach followed suggests a possible
remarkable reduction in product development costs and duration.
The work has been performed within a larger program for the
development of thermoplastic composite materials, with particular
attention to transportation market.
