Quasi-static component testing system Clamping field

Quasi-static component testing system

The institute develops new vehicle concepts and technologies against the background of future requirements for the transport system. The research field of vehicle architectures and lightweight construction concepts researches and develops sustainable construction methods and vehicle structures.

Validation tests of the crash behaviour of components are necessary in the research and development process. Due to the high costs of complete vehicle tests and in the case of new structures, usually non-existent complete vehicle structures, the component crash behaviour is investigated in quasi-static or dynamic component tests.

Component tests can be used to validate simulation models and optimise model behaviour. In order to adapt to the real application, it is important to design the boundary conditions in the component test in such a way that the component behaviour from the overall vehicle environment is simulated with sufficient accuracy. A process model developed at the institute can be used for the time-efficient and requirement-orientated development of robust component crash test benches.

Servo-hydraulic clamping field - Test system details

The testing system is suitable for uniaxial or multiaxial quasi-static tensile and compression tests on components or structures. Test set-ups can be flexibly constructed using existing elements. Angles, T-slot plates and brackets, linear guides, adapter plates, etc. enable the rapid realisation of a wide variety of test set-ups. Load cycle tests are possible within certain limits.
