| Abstract: | The critical speed of rotation of complex rotor is influenced by calculation of its flexural rigidity,which can't be accurately calculated by beam theory. To aim at this problem,the paper introduces aefficient solution-the finite element half-analyzed methods and raises a method that calculates directly critical speed of rotation of complex rotor with the finite element half-analyzedmethod |
