| Abstract: | The effect of two kinds of load factors of bird impact on blade response is analysed in this paper. They are the force-functions and the initial shock pressure. The finite element method is used to compute the nonlinear transient response of the cantilever plate by means of simulating a real blade with a rectangular cantilever plate and simulating bird impact loads with shock loads. The conclusions obtained in this paper may provide references for the development of the bird impact load model. |
