Wind turbine mainframe

For larger wind turbines, stiffness and strength requirements are more difficult to meet. A redesign of the mainframe should result in an economic design with optimal vibration behavior.


Rear wheel carrier

For weight optimization of this chassis component, multiple criteria such as strength, fatigue, plasticity, and stiffness had to be considered.



Higher eco-efficiency is one of the main targets in the automotive industry. To realize a significant weight reduction of a body-in-white, the optimum balance between weight, stiffness, and dynamic behavior is required.
