Cover Story Automobile Construction

At the Institute of Vehicle Concepts of the DLR measures are being investigated for reducing mass by adjusting optimisation strategies for the design and the principal component requirements. On the basis of a selected optimisation strategy, a sill structure is being improved both for specific energy absorption and intrusion into the passenger compartment.

The term lightweight has a very high priority in vehicle development today. The objective of lightweight construction is to meet the requirements that legislators and customers have set for vehicles (e.g. vehicle safety, driving comfort, fuel consumption, costs) at minimal mass. Considering the total energy consumption of vehicles it has been shown that up to 2/3 of this is massd ependent [1]. Thus, a low vehicle mass is an essential factor in helping to reduce the energy consumption of a car.

In the Next Generation Car (NGC) research field at the German Aerospace Center, research into the conceptual design of three new vehicles of...
