Lifetime testing of cylindrical or flat specimens is a technical standard. In contrast, the testing of real components is very cost-intensive and, due to their uniqueness in geometry and stress, a challenge in terms of testing. For the testing of real thin-walled components, a corresponding test rig for high-frequency lifetime testing was designed at the Chair of Mechanical Engineering in advance to this thesis. The test technique includes an outer and an inner system. A relative displacement of the systems causes stress on the component. Since the excitation frequency causes an amplified vibration of the entire internal system, containing the component, the possibility is created to test small components regardless of their natural frequency. To validate the simulation results and to check the functionality, the test methodology must be put into operation. Due to design changes from the original test setup, simulations are performed to investigate the effects. The simulations result in a new natural frequency for the vibration mode to be excited and the acting forces during component loading. The occurring forces are recorded experimentally via a load cell and subsequently compared with the simulation values. By recognizing that a rapid drop in the acting force is evident at component failure, a termination criterion can be introduced for long-term tests. The test can be terminated if the change in force deviates sharply over a short period of time. With the ability to detect component failure, long-term tests are performed at a test frequency of 1440 Hz, at different load levels. The results are visualized as force curves over time with identifiable time points of component failure and compared for the respective load. High relative displacements result in a short lifetime and lower relative displacements result in a longer lifetime. At a reduction of 1 ¿m, the tolerable load changes increase by 3E7. The test setup is therefore very sensitive to load changes, which presents a major challenge in terms of testing. With good comparability of the force curves over time and the appropriate response of the force to load changes, the functional capability is proven. The high-frequency testing technique thus enables component fatigue testing at very high load changes up into the VHCF range.
