The Dynamic Characteristics Analysis of Rotor Blade Based on ANSYS
The three-dimension finite element model of helicopter rotor blade has been built with APDL language. Then using this model, the static strength and the dynamic characteristics about rotor blade has been analyzed with ANSYS software package. During the analysis of dynamic characteristic, the influence of aerodynamic force and centrifugal force applying to blade has been totally considered. Furthermore, the resonant chart of rotor blade has been presented in this paper.
