Design of mechanical products nowadays extensively utilizes simulation models which allow fast design procedure. In this work automotive gage panel (GP) is designed based on Finite Element Model (FEM) and metamodeling. The stationary and transient behaviors of the gage panel under deterministic and random excitations as well as stress distribution under static loading are investigated. Dynamic behavior of the gage panel is obtained by solution of the full FEM models in concordance with the design of experiments. The results of numerical experiments are used for GP frame bracket metamodeling based optimization.
