Advanced Design of Structural Components for Crashworthiness
The passive safety of vehicle occupants and the crashworthy characteristics of the vehicle structural components are issues of growing importance for manufacturers, users and legislators. The demands put in the systems responsible for maximizing safety must be included in the vehicle design, during its early phases, without increasing the time necessary for the designer to come with a reasonably good result. In one hand, the design tools used cannot be so complex and time consuming that different design iteration steps take longer than what is reasonable and, in the other hand, the methodologies used must still be accurate and have low requirements of information. These objectives are achieved by using design methodologies allowing establishing accurate and versatile conceptual vehicle models and by integrating optimization procedures in the reanalysis process in order to support the decisions.
