Study on the Damping Mechanism of the Shrouded Blade considering Contact Features by Chaofeng Li, Tao Li, Ruihuan Qiao, Bangchun Wen

“…The influence of shroud structure’s parameters such as rotational speed, contact angle, friction coefficient, clearance, and shroud position on the damping effect of the shroud is reviewed by means of amplitude-frequency response and energy through the Newmark-β numerical method. The results demonstrate that the damping effect of the shroud by contact is more obvious than by friction and the amplitude-frequency curve of the shrouded blade shows a strong hard nonlinear phenomenon.…”
