The　frequency　veering　of　a　metal　porous　rotating　cantilever　twisted　plate　with　twist　angle　and　stagger　angle　is　investigated.Metal　porous　materials　may　have　the　characteristics　of　gradient　or　uniform　distribution　along　the　thickness　direction.Based　on　the　classical　shell　theory,considering　the　influence　of　centrifugal　force　produced　by　high-speed　rotation,the　free　vibration　equations　of　a　rotating　cantilever　twisted　plate　are　derived.Through　the　polynomial　function　and　Rayleigh-Ritz　method,the　natural　frequencies　and　mode　shapes　of　the　metal　porous　cantilever　twisted　plate　in　both　static　and　rotating　states　are　derived.The　accuracy　of　the　present　theory　and　calculation　results　is　confirmed　by　a　comparison　between　them　and　the　results　available　from　the　literature　and　those　obtained　from　Abaqus.The　influences　of　the　thickness　ratio,porosity,twist　angle,stagger　angle　and　rotational　velocity　on　the　frequency　veering　and　mode　shape　shift　of　the　rotating　cantilever　twisted　plate　with　porous　material　under　three　different　distributions　are　analyzed.It　should　be　mentioned　that　the　frequency　veering　accompanied　by　mode　shape　shift　occurs　in　both　static　and　dynamic　states.
