Abstract

An innovative approach to dynamic design is presented that has the notable advantage of allowing the dynamic requirements to be specified from the earliest design stage. The method applies genetic algorithms to optimize the dynamic behavior of the engine-cradle system and its links to the chassis. The optimization minimizes the sum of the amplitudes of the forces transmitted to the chassis, while complying with the static and dynamic constraints. The genetic algorithm was applied to a multibody system model of the engine-cradle system and its links to derive new, improved configurations.
