To　improve　the　vibration　reduction　effect　in　low-frequency　band　of　dynamic　vibration　absorber　(DVA),　a　novel　type　of　articulated　silicone　gel　column　(SGC)　is　introduced　in　the　design　of　the　tuned　dynamic　vibration　absorber.　The　nonlinear　variation　of　frequency　of　SGC　with　varying　geometry　is　obtained　by　both　finite　element　simulation　and　experiments.　The　most　sensitive　mode　is　located,　which　has　a　wider　frequency　range　by　varying　the　geometry.　The　polynomial　fitting　is　used　to　describe　nonlinear　relation　between　frequency　and　geometry.　By　tuning　the　geometry,　the　equivalent　stiffness　and　then　resonance　frequencies　can　be　manipulated　to　behave　as　an　active　vibration　absorber.　The　vibration　reduction　experiment　of　SGC　vibration　absorbers　is　investigated.　It　is　found　that　SGC　has　better　vibration　reduction　effect　in　the　low-frequency　band.　The　experimental　results　in　the　current　design　demonstrate　that　the　vibration　reduction　effect　can　reach　94.03%　when　tuning　SGC　to　the　first-order　main　resonance.　The　dimensions　and　material　parameters　of　SGC　should　be　altered　for　the　specific　frequency　range　and　vibration　strength.
