Abstract :
The dynamic response of rotating blade with pre-twisted angle and variable cross section in non-inertia coordinate system is presented in this paper. Based on Lagrange equation, the dynamic equations of rotating blade with pre-twisted angle and variable cross section are derived and discretized using finite element method. The numerical simulation results of the above equations by Newmark method revealed the significant effects of rotating angular velocity and pre-twisted angle on vibration displacement response of blade.
