Variable Amplitude Loading on a Resonance Test Facility

Source

The uncertainty in fatigue lifetime calculations brings up the necessity of experimental verification. Several efforts have been undertaken in the past to improve and introduce new test methods. An alternative method for variable amplitude loading using resonance test facilities is introduced and discussed. A comparison of test results on a resonance test facility with a new control system and a servo hydraulic test facility shows no significant difference in the test results. The compatibility of the test results to those results of accepted fatigue life tests is proven for three test series of different specimens. The introduced resonance test control offers a new way for fatigue life tests, reducing the cost and time, as well as increasing the safety of products because it permits testing to much longer lives in a relatively short time.
