2. Introduction • Two results are analyzed, standard deviation to indicate pressure uniformity and average pressure • Presentation Outline • Present data • Justify ANOVA assumptions • Analyze significant factors • Analyze interactions • Conclusions

3. Comparison of Average Pressure and Standard Deviation across Skew Angles

4. Signal to Noise Ratios • S/N = µ/σ = Std Dev/Mean

5. Average Pressure vs. Skew Angle Note: Standard deviation is not the analysis of variance between these average pressure data points. It is the analysis of pressure variations across the entire scan.

21. Conclusions • Abaqus model was on target • Experimental results point to 1.91° as the optimal skew angle to maximize pressure uniformity • The average pressure value changes based on the configuration, but several configurations fell in the acceptable pressure range

22. Optimal Design • Standard Deviation • Main Effects: 1.9 deg, portrait, 130 lbs, k=270 • 2nd Order Effects: 1.9 deg, portrait, 170 lbs, k = 270

23. Optimal Design • Average Pressure • Main Effects: • Load is variable but ~140 lbs, • Orientation is variable, no specified preference • Compliance is variable but ~415 lbs/in, by interpolation • Interaction effects agree with main effects, except landscape orientation is preferred • P-value for the average pressure DOE is 0.105 • P-value for the standard deviation DOE is 0.000
