Adapted Fatigue Calculation for New Lightweight Designs of Rotating Suspension Components 2006-01-3512
The main goal of lightweight concepts are the improvement of cost efficiency and production processability. To guarantee still a sufficient operating safety of these new designed components an increasing effort during the development process is required. Numerical structural durability analysis methods give us the possibility to identify the changed fatigue sensitivity and behaviour of these new designs to the different service loads and assembly conditions. And most important, necessary modifications for existing numerical and experimental design concepts can be derived.
In the following on a example of new lightweight heavy truck wheel hub the results of a joint project using a special numerical concept are presented.
