众所周知,较大的风荷载不仅对桥上行驶的车辆产生巨大的噪音,对其安全都会构成一定的威胁;横风是高速车辆的威胁之一,高速车辆在横风的作用力下,具有发生倾覆的危险,强风作用严重限制了车辆的运行速度。同时,风力也是一种能量,公路桥梁的上风力一般较大,对通过桥梁上的风能不能充分利用,也是一种浪费。为保持车行驶的稳定性,同时充分通过桥梁上的风能,作者设计出了具有发电消音功能的桥梁挡风屏,具有结构复杂,安装方 It is well-known that larger wind loads not only cause huge noise to vehicles traveling on the bridge, but also pose a certain threat to their safety. Crosswind is one of the threats of high-speed vehicles. Under the action of cross-wind, The danger of capsizing and strong winds severely limits the speed of the vehicle. At the same time, the wind is also a kind of energy, and the wind power of highway bridges is generally large. It is also a waste of wind energy that can not be fully utilized through the bridges. In order to maintain the stability of the vehicle driving and at the same time to fully pass the wind energy on the bridge, the author designed a bridge windscreen with power generation silencing function, which has the advantages of complex structure,
