Multi material design (mmd) represents the ideal compromise for the automotive lightweight design of the future with its capability of weight-reduced components at acceptable costs and practicability in large-scale production. At present, there are only limited selection strategies available for the goal-oriented identification of potential multi material areas in the vehicle. In order to develop a selection strategy for potential areas of application of the design method, the properties and conversion factors of existing components in hybrid construction methods from the automotive industry and research were investigated.
In this contribution, the relevant influencing factors from component design, material selection, production and joining technology as well as cost planning are identified and their interaction is investigated. Based on a Pareto-Analysis in combination with the evaluation of a component study, significant effects could be identified regarding structural automotive components in mmd. The identified effects and their interaction are classified into a network of dependent variables. The “Network of mmd potentials” serves as a result of this contribution the basis for the development of an regression model for the indication of the feasibility of components in mmd.
