Abstract
This paper describes an optimal tuning method for swing reduction of a gondola lift by a pendulum type dynamic absorber. The fixed point theory used for the design of the conventional dynamic absorber modeled as a mass connected with a main rectilinear vibration system by a spring and a damper are first examined in detail. Behavior of two fixed points of the pendulum type dynamic absorber attached to a pendulum type main system is next investigated. As a result it is found that behaviors of these fixed points are different from that of the conventional dynamic absorber and that the optimal tuning can be obtained by choosing a cerain value of inertia ratio of the dynamic absorber to the main system. It is also found that the maximum value of the amplification factor can be decreased without limit as the natural frequency of the dynamic absorber is decreased. Theoretical results are confirmed by experiment.
