Supports are one of the most popular structural elements in engineering. They have a wide range of applications, including in pressure gauge connectors, fixtures for photovoltaic and solar panels, and traffic signs. Supports are also used in highly complex engineering projects such as airplane wings or rotor blades. Monitoring methods for detecting and predicting the condition of support structures have become an important area of research. Structural damage to machines and machine parts can be prevented through early detection of fatigue cracks with the use of non-destructive methods. The paper proposes a method for detecting fatigue cracks along the cross-sectional area of a specimen based on selected parameters of the vibration signal. The diagnostic signal for analyses of specimen cross-sectional area was vibration acceleration, which was described with the use of the following parameters: changes in amplitude and waveform (FFT), RMS amplitude, changes in the amplitude of a vibrating sample, and changes in the phase angle of a vibrating sample. In the test stand, cross-sectional damage was caused by forces of inertia acting on the specimen. The results of the study indicate that all of the analysed parameters can be used to detect the loss of structural continuity (mechanical and fatigue cracks) in an object. An analysis of changes in the amplitude of a vibrating sample was the fastest and most comprehensive source of information.
