Abstract:
A set of multidisciplinary topology optimization (MTO) and fast validation method
is discussed, which can be applied in the car body concept design stage. First,
considering seven typical loading cases, optimized load path is obtained by MTO.
Then an equivalent car body model is built up with new load path. In order to
verify its linear and nonlinear performances quickly, original and optimized
path models are established, respectively, by using macro elements. The results
show that rigidity and collision performance of the optimized path are better
than that of the original one. In the meantime, reduce the validation time from
hours to minutes.
