Due　to　strong　nonlinear,　unsteady　characteristics　and　the　fluid-structure　interaction　effect,　vibration　analysis　of　blades　under　the　excitation　of　the　airflow　is　still　one　of　the　technical　difficulties.　In　this　paper,　the　accurate　subsonic　aerodynamic　force　is　obtained　through　numerical　simulation,　and　the　aerodynamic　coupling　model　of　the　rotary　blade　is　established.　The　distribution　of　the　aerodynamic　force　of　the　compressor　blade　under　the　unsteady　airflow　is　focused　on.　The　blade　is　modeled　as　presetting　a　presetting　pre-twisted　rotary　cantilever　plate.　Dynamic　frequencies　of　the　plate,　calculated　by　Chebyshev-Ritz　method,　are　compared　with　frequencies　calculated　using　the　finite　element　method　(FEM).　Effects　of　different　parameters　on　natural　frequencies　of　the　rotary　plate　are　discussed.　Based　on　von-Karman　nonlinear　geometric　relation　and　the　first-order　shear　deformation　theory,　nonlinear　dynamic　equations　of　the　pre-twisted　rotary　plate　under　the　combination　of　the　centrifugal　force　and　the　aerodynamic　are　derived　by　utilizing　Hamilton＇s　principle.　Second-order　ordinary　differential　equations　are　derived　by　applying　the　Galerkin　method.　Analytical　solution　of　the　dynamic　deformation　of　the　plate　is　presented　and　is　compared　with　that　produced　by　FEM.　Results　indicate　the　accuracy　of　the　explicit　presentation　of　the　aerodynamic　of　the　low-pressure　compressor　blade.　Effects　of　the　rotary　speed,　the　thickness,　the　pre-twisted　angle　and　the　presetting　angle　on　vibration　characteristics　of　the　warping　blade　are　studied.　Mode　shape　shift　and　frequency　loci　veering　are　discussed.
