Wind shielding device capable of effectively restraining vortex-induced vibration of split type box girder and using method of wind shielding device
According to the wind shielding device capable of effectively restraining vortex-induced vibration of the split type box girder, under a certain wind speed, the amplitudes of wind-induced vibration of the girder caused by the wind shielding plates in different directions are different, and by rotating the wind shielding device, a blocking effect can be formed on incoming wind, so that a flow field around the girder is changed, and the vortex-induced vibration effect of the girder is improved; by rotating the wind shielding device, the height of the wind shielding plate can be reduced, namely the wind resistance effect is enhanced by the two resistance increasing plates perpendicular to the wind shielding plate at the same wind speed, and local backflow is formed for incoming wind; the wind shielding device is simple and easy to control, a better effect of restraining wind-induced vibration can be obtained by simply rotating the wind shielding plate, and input energy is little.
本申请提供一种可有效抑制分体式箱梁涡激振动的挡风装置，在一定风速下，不同方向的挡风板对主梁风致振动的振幅不一，通过旋转挡风装置，可对来流风形成阻挡作用，以此改变主梁周围的流场，从而改善主梁涡振效应；通过旋转挡风装置，可减小挡风板高度，即同样风速上垂直于挡风板的两个增阻板对增强了风阻效果，对来流风形成了局部回流；挡风装置简单，易于控制，通过简单的旋转挡风板，就能获得更好的抑制风致振动的效果，且输入能量少。
