With an increasing demand to reduce the product development time
cycle from concept-to-vehicle, weight saving effort and less
prototype initiative, CAE evaluation technique in the vehicle
durability development must allow the computer simulation to
reproduce the actual driving condition over a proving ground.
This paper describes the case study to predict the durability
performance of full vehicle using vehicle FE parts in ADAMS model.
The objective is to carry out full vehicle simulation in actual
road load condition using reduced full vehicle FE model, condensed
with the ADAMS model. The measured acceleration is applied to the
vehicle FE model and dynamic loads converted to equivalent static
loads. The FE model solved in MSC.Nastran® with number of static
load subcases converted from the measured proving ground road
data.
It also verifies the validity of the evaluation methodologies by
simulation-to-experiment comparisons. The validation demonstrates a
high correlation with experiment and a viable CAE evaluation of the
durability performance.
Two case studies will be presented to show the application of
this methodology to full vehicle systems for vehicle durability
applications.
