BMW Robust Design Quest

摘要

When optimizing crank-case fatigue life and gasket behavior, BMW Motoren Gmbh needed to resolve the problem of noise affecting uncertain variables in the design process. The engineering team noticed that solutions which performed well at concept level did not pass the validation stage due to unforeseen factors. To tackle this issue the team considered the uncertainty related to certain input parameters which could not always be precisely determined under real manufacturing and operating conditions. Moreover, a product designed for a specific scenario was not suitable for other environments. Therefore, they looked for a way to come up with designs with a lower variability of performance.
