STUDY ON A MECHANICAL SEMI-ACTIVE VIBRATION ABSORBER AND ITS CONTROL STRATEGY

摘要：

In this study, a mechanical semi-active vibration absorber (SAVA) was developed whose natural frequency can be adjusted in real-time by simple adjusting the geometry parameters of the absorber. An optimum variable step-size control strategy was studied. This control strategy is made up by two stages: the roughly tuning stage and the optimization stage. The dynamic properties of the SAVA were characterized on a clamped-clamped beam. The results indicate the developed SAVA can change its natural frequency in a large frequency range and its vibration absorption capability is significantly improved compared with conventional tuned semi-active vibration absorber;optimum variable step-size control;vibration controlvibration absorber.
