摘要
A new model for an untuned damped vibration absorber is put forward here in accordance with some actual mechanical structures,and its performance or responses to various system parameters of the model are also fully discussed.Generally speaking,machines should be designed to avoid working at their resonant frequencies.For some modern machines their working speeds often exceed their first even second resonant frequency,so,it is the same important for them to pass through their resonant frequencies steadily during starting or shutting down.In the paper the max peaks of the main system vibration amplitude and force transmissibility,as well as their corresponding peak frequencies are emphasized.
