Crashworthiness improvement of a pickup truck's chassis frame using the Pareto-Front and genetic algorithm

In this paper, a methodology is presented to derive the relation between minimum structural weight and maximum impact energy for crashworthiness improvement. The methodology is based on the principle of the Pareto-Front and multiobjective optimisation technique. The designer can then use the derived relation to evaluate the crashworthiness performance of any suggested design easily and effectively. Moreover, providing a set of optimum solutions offers the designer more flexibility in optimising the performance of the initial design. The capabilities of the new methodology have been successfully demonstrated on a simple thin-walled tube and a chassis frame in a pickup truck.
