Abstract

Based on the theory of finite rotation beam, together with the finite element method, the rotor dynamic model is established, and the relationship of strain and displacement in the strain energy of blade is solved by introducing the generalized Danielson-Hodges strain and Green-Lagrange strain. The three-dimensional nonlinear analysis is decoupled into two-dimensional linear profile analysis and one-dimensional nonlinear blade analysis. Hartenberg-Denarit augmented transformation matrix is introduced in kinetic modeling. According to the Hamilton principle, the nonlinear implicit dynamic equations of the rotor are established. Blade flap under the influence of gust wind is calculated; the safety criterion of the ground starting of the helicopter is put forward.
