The paper presents the assessment results of probability of detection for damages in mechanical structures conducted with a Structural Health Monitoring (SHM) system based on the measurements of electromechanical impedance. The research was carried out with both numerical models and real-life mechanical components. The results of laboratory tests performed in operational conditions for a bolted pipeline connection confirmed usefulness of both the applied monitoring method and the SHM system. The hit/miss and signal response statistical approaches were employed to gain insight into the specific SHM system reliability.

W artykule przedstawiono wyniki oceny prawdopodobieństwa wykrycia uszkodzeń w konstrukcjach mechanicznych dla systemu monitorowania stanu technicznego opartego o pomiary impedancji elektromechanicznej. Badania przeprowadzono zarówno dla modeli numerycznych jak i rzeczywistej konstrukcji mechanicznej, której stan techniczny monitorowano z zastosowaniem opracowanego systemu. Wyniki laboratoryjnych testów działania sytemu uzyskane dla monitorowanego połączenia kołnierzowego części rurociągu potwierdziły przydatność zarówno zastosowanej metody jak i zbudowanego systemu w obszarze monitorowania stanu technicznego konstrukcji mechanicznych. Do oceny prawdopodobieństwa wykrycia uszkodzeń zastosowano techniki statystyczne hit/miss data oraz signal response data.
