Future Work - Global Gauge<br />
Sensitivity Indices<br />
• Investigate the possibility of defining a global λ based upon forced dynamic response,<br />
including compliance frequency response, and crash.<br />
• Develop the analytical background (calculation methodology, weight savings<br />
predictions) for a global λ based upon a variety of body stiffness metrics (e.g., closure<br />
distortions).<br />
• Use CARS/GAS and other tools to continue to investigate the influence of thin-wall<br />
effects on λ behavior and interpretation.<br />
• Conduct comparative global gauge sensitivity studies for a variety of passenger car and<br />
truck bodies.<br />
• Determine the nature and magnitude of the errors induced by the assumption that<br />
responses are exactly proportional to a constant times “t” to the “λ”(C*t λ ).<br />
• Continue to investigate the use of global λ curves to assess the effectiveness of local<br />
architecture changes.<br />
