In view of the shrouded structure system of power turbine blades of the turboshaft/turboprop engine and its reliability to processing errors, changes in working load environment and wear and damage to the contact surfaces between shrouds were analyzed. A blade vibration analysis model considering variability of contact surface of the shroud working surface on the contact stiffness of the interface was established, and the probability of fatigue fracture failure of the structural system was evaluated. Simulation results indicated that joint effect of processing errors and interface wear and damage can cause a decrease in the vibration frequency of the blade. This causes the resonant rotational speed of the blade in this vibration mode to deviate from the design value and intersect with the operating speed range, resulting in the risk of resonance and high-cycle fatigue failure, thus reducing the reliability of the structural system.
