Research on the power and anti-vibration characteristics of damper

In this paper, the lumped-mass mechanical model of the damper is established after force analysis. The effects of the structural parameters on the power characteristics of damper are discussed. And the power characteristic experiment is carried out in the laboratory. The experimental results are well agreed with the theoretical ones. Additionally, the nonlinear motion equation of the transmission line with a damper which is simplified into mass-spring-damping system is constructed. The frequency response curve is obtained by multiple scale method. The effects of the stiffness and damping of the damper to the transmission line are studied. The results of the vibration characteristic of damper can provide a basis for the optimal design of the dampers.
