Modeling and Simulation of Frontal Crash Impact Response 810793
The capability to predict the response of a vehicle body structure to frontal barrier crash is examined by a vehicle model represented by various lumped mass and non-linear resistance systems from that of one dimensional with minimal degrees of freedom to these of two dimensions and several degrees of freedom.
Comparison between numerical calculation and full scale experiment demonstrates that on even a simple representation, the calculations are in good agreement with the experiment.
Several methods of obtaining the resistance characteristics based on full scale experiments and quasi-static component crush testing are also presented.
Further, distinctive characteristics and subjects to be considered of front wheel drive vehicle compared with front engine rear wheel drive one on passenger compartment integrity and occupant restraint performance are discussed.
