MultiMaK2 – Design and development of assessment tools for ecologically optimized multi-material automotive components for mass production

Initial Situation

In the automotive development, stringent emissions legislation and increased system weights foster the need for consistent lightweight vehicle. Traditional materials and construction methods reach their limits, so that the high-volume use of lightweight materials (hybrid materials) is pursued intensively. However, multi-material construction methods affect the entire vehicle concept. In addition, the production of of some lightweight materials lead to increased energy and resource consuption.

Objective

Improved methods and tools for integrated (economic, ecological, technical) evaluation of products and process chains are developed for multi-material components with high manfacturing volumes. Taking into account the energy and material flows in production and life-cycle effects in different usage scenarios, design rules for products and processes as well as concrete component concepts are to be derived. These are anchored in the framework of a Life Cycle Design & Engineering Labs in the LABfactory.

Approach

  • Definition of use case scenarios for vehicles
  • Evaluation of different lightweight design strategies for automotive functional modules
  • Development of a Life Cycle Prediction Models
  • Derivation of guidelines and rules for hybrid materials lightweight design
  • Design of optimal component concepts for selected modules
  • Development of a software tool for the decision support in component design
  • Establishment of a Life Cycle Design & Engineering Lab
  • Analysis of the energy- and resource efficiency of manufacturing processes
