| Abstract: | An analysis of the free vibration problems of turbine single blade and shroud as well as lacing wire-connected blade groups has been undertaken by employing a coagulative impedance matrix integrated method involving finite element dynamic substructures. Specific computation procedures and calculation examples are given. Eight-node curviplanar superparametric shell unit is utilized for blade discretization. Calculation results have shown that the coagulative impedance matrix integrated method is easy to use and features a relatively high precision when it is applied for the vibration analysis of complicated structures. |
