Development of highly dynamic test cylinders for test benches

Overview

Within the scope of the project, a new type of hydraulic test cylinder with self-adjusting control system is to be developed. The the focus is on the dynamics of the cylinder, to enable it to be used as a load unit in service life test rigs. Conventional hydraulic cylinders have too narrow a bandwidth have too narrow a bandwidth with regard to displacement control, which is why the reference loads are set using must be set with the aid of iterative learning learning procedures. However, this procedure is time-consuming and and cost-intensive, and in addition it can lead to pre-damage or destruction of the test specimen cannot be ruled out. Therefore there is need for further action and research for controlled test cylinders that can meet the dynamic and and accuracy requirements of modern testing systems.
