ABSTRACT
An automated system for recording of the number of cycles of the flexural vibrations till the fracture of the sample has been developed. The H2-7EA3 measuring device was used as a counter. This device has high noise immunity and memory, which is important in case of a power failure or a voltage surge. Based on experimental data, obtained using the proposed installation with an automated system counting the number of cycles, endurance limit of aluminum has been estimated.
