Multi-attribute evaluation of concept variants for lightweight structures

The design and evaluation of lightweight structures is a multi-step process that involves several different attribute evaluations. In the early design phase, specific functions of the structure have to be decided, geometry may not yet be fixed and materials must be assigned. Only rough values of attributes such as mass, stiffness and Noise, Vibration & Harshness (NVH) behavior can be estimated. On the other hand, in the final design process, full finite element models predict detailed product performance. The links between early design decisions and final product performance are not always apparent. More importantly, the variation of different concept models, which are most efficiently evaluated in the early design stage, must also be correlated to final design specifications. This work aims at defining a work-flow for the multi-attribute evaluation of concept variants, using a lightweight car door as an example.
