In the EU research project ”epsilon”, the Fraunhofer Institute for Structural Durability and System Reliability LBF has been tasked with the development, manufacturing, and testing of a hybrid lightweight rear axle. The main focus of the development was reducing mass while maintaining safety under operating conditions.
Lightweight design plays an important role for the emerging electromobility. The significant increase in weight due to the necessary batteries is an enormous challenge for vehicle manufacturers. For this reason, a growing number of companies aim to optimise weight and use innovative solutions to do so. Thus, new materials, design concepts, and manufacturing processes have been introduced to the automotive sector over the last years. Increasingly, components of the structure (i.e. the car body) and of suspension systems traditionally made of metal are being replaced by those made of fibre reinforced polymers.
In doing so, it is important to determine, whether...
