Optimization of a Clutch Disc Torsional Damping System Design 2002-01-3389

1

During the development of a new clutch disc damping system and after three months of hard work the engineering team got stuck with unsatisfactory system performance (rattle noise), despite the help of a computer simulation software. The only alternative seemed to be using a more expensive damping concept but, besides the fact that there wasn't much development time left, that option would increase part cost by unacceptable US$ 200, plus development cost. The team then decided to try Taguchi's Robust Engineering optimization approach for the first time. In just two weeks the authors got a 4.6 dB gain on the signal-to-noise ratio. That allowed us to keep the initially proposed system, thus avoiding the cost increase. Besides, the authors were able to keep the development schedule on track. And perhaps even more important, the authors can now more effectively apply our engineering knowledge and make a better use of the computer simulator, which results in a faster and more reliable development process.
