A vehicle frame includes first and second lower rails and first and second upper rails operatively interconnected. Cross members horizontally interconnect the lower rails and the upper rails, and stanchions vertically interconnect the upper rails and the lower rails. The frame provides improved stiffness and strength at a reduced mass compared to the prior art.

A method for calibrating a physical test cell includes the steps of: determining a set of inputs to be provided to the physical test cell based in part on a set of historical test data; providing the inputs to the physical test cell and receiving a set of outputs associated therewith, wherein the providing includes implementing a sequential space filling sampling procedure to substantially cover a region defined by the set of historical values; creating a virtual test cell comprising one or more response surfaces based on the set of outputs; and interrogating the virtual test cell to determine a calibration relationship between at least one of the inputs and at least one of the outputs. Smooth Kriging may be used to determine the virtual test cell.
