Abstract A novel dynamic vibration absorber(DVA) model with negative stiffness and inerter-mass is presented analytically studied in this paper. The research shows there are still two fixed points independent of the absorber damping amplitude frequency curve primary system when contains inerter-mass. optimum ratio obtained based on fixed-point theory. In order to ensure stability system, it fou...

Abstract An adaptive dynamic vibration absorber (ADVA) is designed for low-frequency suppression. The leaf springs are applied as the tuning stiffness elements. principle of variable analyzed to obtain effective range first natural frequency variation. A classic simply supported manipulator selected controlled system. coupled model manipulator-ADVA system built maximum damping efficiency and ab...
