Automotive vehicle gage panels must meet many requirements starting with appropriate design style and precisely measurable functional characteristics such as stiffnesses, stress levels under loads, weight, accuracy, eigenfrequencies etc. and last but not least with minimal environmental pollution. Design styling is less easily measured concepts and frequently is handled informally. The method of imprecision is used to allow for a formal approach to the incorporation of this imprecise information. Geometrical models of the gage panel are elaborated by SolidWorks (SW) and style is designed by SW PhotoView360. Static and dynamic responses of the gage panel are calculated by SW Simulation and impacts to environment are evaluated by SW Sustainability. Due to complexity of FEM models appropriate metamodels are elaborated based on design of experiments [1, 2]. These metamodels are used for multiobjective optimization. Partial objectives are aggregated in complex objective function for optimization purposes. Pareto frontiers are built for choosing the final solution. Dynamic behavior of the gage panel for some points of obtained Pareto set is then verified by solution of full FEM models in the case of random vibrations as well as sensitivity analysis is done.
