Structural Health Monitoring is becoming more and more important for today's railway. Higher requirements are set for safety and availability of both trains and tracks, that can be achieved using new type of SHM systems. Proposed SHM system is based on vibration measurements during the rail vehicle operation simultaneously with GPS position and velocity estimation. AIgorithm for rall track health assessment is formulated as inverse identification problem of dynamic parameters of rail - vehicle system. Track irregularities of tracks are identified using this procedure. The case study of the SHM system operates on rail vehicle is presented in the paper.

Monitorowanie stanu staje się coraz bardziej istotne dla dzisiejszej kolei. Wyższe wymagania są ustalane dla bezpieczeństwa i dostępności zarówno dla pociągów jak i torów, które można osiągnąć za pomocą nowego typu systemów SHM. Proponowany system SHM opiera się na pomiarach drgań w czasie eksploatacji pojazdów kolejowych jednocześnie z pozycji GPS i oszacowania prędkości. Algorytm oceny stanu toru kolejowego jest sformułowany jako inwersja problemu identyfikacji parametrów dynamicznych system tor - pojazd. Nieprawidłowości toru są identyfikowane za pomocą tej procedury. W artykule przedstawiono rozważania działania systemu SHM w przypadku pojazdu kolejowego.
