Robust Design Optimization of a rubber seal
RDO on global response surface
• Optimization variables are varied in optimization space
• Pure stochastic variables are varied +/- 4 sigma
• 200 LHS samples generated with uniform distribution
• Approximation quality between 93% and 97%
• Young’s modulus is in RDO space
minor important but in robustness
space most important
� Pure stochastic variables
are unimportant
� Poor local approximation quality
for robustness analysis
