ENERGY ABSORBING VOLUME AND DESIGN OPTIMIZATION FOR POSSIBLE CAR WEIGHT REDUCTION AND BETTER FUEL ECONOMY

Weight reduction and fuel economy demand the maximum exploitation of car structures to the end of absorbing energy in case of collision. The available volumes are considered, i.e. front section (front collision), rear section (rear collision), side section (side collision). The maximum deformation work each section can absorb, before compartment collapse, is determined. A comparison is made of the deformation corresponding to such a limit and the one measured in collision tests, thus determining the amount of structure utilization in each type of collision. The evaluation of the extent of available structural volume which is actually exploited provides a clue to the design optimization and a possible car weight reduction. (Author/TRRL)
