Abstract
Conventional linear viscous damper has the trade-off characteristics between vibration suppression effect of peak resonance amplitude and increase of vibration between resonance points. In this paper, the nonlinear dampers to solve such problems are proposed and investigated. Two kinds of nonlinear dampers, power series type and step function type, are proposed and set between mass points of two-degrees-of-freedom system. From theoretical results, it is clarified that some types of power series type nonlinear dampers and step function type nonlinear damper not only suppress the peak resonance amplitude but also avoid the increase of vibration between resonance points.
