Abstract
A new resonance-regulated testing device operating at a frequency of up to 200 Hz has been developed for very high cycle fatigue tests on large-scale cast iron and steel specimens. The device is able to perform tests on axially loaded plate specimens with a thickness of up to 20 mm and a width of up to 40 mm. It allows testing with a maximum amplitude of 70 kN and a stress ratio of 0.1 ≤ R ≤ 0.5. In this paper, the working principle of the device is shown. Furthermore, the calibration, pretension, and testing procedures, as well as the results of the first fatigue tests, are presented based on tests with ductile (grade EN-GJS-400-18C-LT) cast iron.
