| Abstract: | Described in this paper is an analytical model for calculating the natural vibration characteristics of a blade disc coupled system. Through the use of the cyclic symmetry function of a finite element general program NASTRAN and the function of geometrical nonlinearity a computational analysis has been conducted of a naval gas turbine blade disc structure. During the calculation, the effect has been taken into account of the rotating centrifugal force and temperature dependent material parameters on the natural characteristics. The obtained harmonic resonance vibration frequency is found to be in basic agreement with the experimental results. |
