Developing an Automated Design Modification System for Aluminum Disk Wheels

This paper presents an automated design modification system that integrates engineering analysis results and common redesign strategies of engineers with a fuzzy logic algorithm in order to provide effective strategies to reduce the failure probability. The probability model is described first followed by providing engineers´ common strategies for redesigning the wheels. Sensitivities of the strategies with respect to the probability of fatigue failures have been calculated to evaluate these strategies. A set of fuzzy rules on how to reduce the failure probability using these strategies is established, and an automated design modification system is constructed. Finally this system is validated using 3 real wheel design examples. Using this system, designers´ previous experience can be properly preserved and shared with all designers
