A Numerical Approach for the Resonance Passage Computation

Abstract

This paper describes a numerical approach to compute the passage through the resonance with one of the natural frequencies and provides analytical proof of this. The numerical approach was used to compute the resonance passage of a turbine blade. The results are compared with complete resonance passages of a simplified multi body model and showed a very good agreement with the test results. In addition some parameter studies, such as structure damping resonance passage time and excitation amplitude, are presented.
