PT Journal AU Vavro, J Vavro, J Kianicova, M Vavrova, A Pecusova, B TI Numerical Modal Analysis of the Turbo-jet Engine Rotor Blades SO Manufacturing Technology Journal PY 2019 BP 1067 EP 1070 VL 19 IS 6 DI 10.21062/ujep/419.2019/a/1213-2489/MT/19/6/1067 DE modal analysis; eigenfrequencies; eigenshapes; stress; finite element method AB The given paper is closely connected with the numerical modal analysis of eigenfrequencies and eigenshapes for turbine blades of the turbojet engine with the help of the mathematic modelling. The mathematic model was created in Pro-Engineer program and it was subsequently created to the ANSYS program in order to apply finite element method. Distribution of the stress in the turbine blades is presented in [Pa]. The presented results of the eigenshapes and distribution of the stress are obtained in the graphic form. ER
