Double-synthetic-jet damping protection device of cylindrical structure
The invention discloses a cylindrical structure double synthetic jet damping protection device which comprises jet slits and a jet channel, the jet slits are located near a flow separation point on the surface of a protected cylindrical structure, the number of the jet slits is two, the two jet slits are symmetrically distributed on the surface of the cylindrical structure in the incoming flow direction, and the jet channel is communicated with the jet slits. The jet flow channel is arranged in the cylindrical structure and penetrates through the whole cylindrical structure, the inner side of the jet flow slit is communicated with the jet flow channel, one end of the jet flow channel is movably connected with an external piston, and the piston is driven by a servo motor. According to the double-synthetic-jet vibration reduction protection device of the cylindrical structure, a good control effect can be achieved on wind-induced vibration of the cylindrical structure.
本发明公开了一种圆柱形结构的双合成射流减振防护装置，包括射流狭缝和射流通道，射流狭缝位于被防护的圆柱形结构表面的流动分离点附近，射流狭缝设有两个，两个射流狭缝沿来流方向对称分布于圆柱形结构的表面，射流通道设置在圆柱形结构的内部并贯穿整个圆柱形结构，射流狭缝的内侧与射流通道相通，射流通道的一端与外部活塞活动连接，活塞由伺服电机驱动。本发明采用上述一种圆柱形结构的双合成射流减振防护装置，能够对圆柱形结构的风致振动产生良好的控制效果。
