...Haimin Zhu; Wenye Wu The flexible shafts in aviation equipment experience severe vibration upon exceeding the critical speed, causing severe damage to the equipment. To address this issue, a novel technique for vibration reduction using a multi-gap limiting ring device is proposed. The coupled...

... of the seat track by more than 70% during the autostarting and stopping of the engine. The initial crank angle can have an effect on the seat track vibration as well. hybrid vehicle autostart/stop powertrain dynamic simulation vibration reduction Hybrid electric vehicles (HEV) have lower...

...Walid Larbi; Jean-François Deü; Monica Ciminello; Roger Ohayon In this paper, we present a finite element formulation for vibration reduction in structural-acoustic systems using passive or semipassive shunt techniques. The coupled system consists of an elastic structure (with surface-mounted...
