| Abstract in different language: | The paper deals with 1D finite element modelling of a turbine blade. The proposed finite element has only 16 degrees of freedom (DOF) and enables to achieve a complex model of turbo-machine with a relatively small DOF number, more details will be described in the article. It is a great advantage but the pre-processing for the blade cross section parameters of the individual blades is a little bit more complicated. This approach means to solve a warping function in chosen cross sections of the blade and simultaneously calculate the geometrical parameters of those cross sections. The second step represents an approximation of the obtained parameters along the axis coordinate ? by means of spline functions. The next step is gradual computation of local finite element matrices and assemblage of the global blade matrices. |
