Vortex vibration and flutter prevention device and split type box girder bridge
The invention provides a vortex vibration and flutter prevention device and a split box girder bridge and relates to the technical field of bridges, the vortex vibration and flutter prevention device is used for being installed between two adjacent split box girders and comprises a vortex isolation plate, a fixing plate, an anemograph, a control system and a driving system, and the anemograph, the control system and the driving system are installed on the fixing plate; the vortex isolating plate is rotationally connected with the fixed plate, and has an initial state parallel to the fixed plate and an overturning state perpendicular to the fixed plate; the control system is in signal connection with the anemograph and the driving system; the anemograph is used for detecting wind speed; and the driving system is in transmission connection with the vortex isolating plate, so that the vortex isolating plate is switched from an initial state to an overturning state. The technical problem that remarkable vortex-induced resonance is likely to happen to the grooved box girder is solved.
本发明提供了一种防涡振和颤振装置及分体式箱梁桥梁，涉及桥梁技术领域，该防涡振和颤振装置用于安装于相邻的两个分体箱梁之间，包括隔涡板、固定板和安装于固定板的风速仪、控制系统和驱动系统；隔涡板与固定板转动连接，且具有与固定板平行的初始状态和与固定板垂直的翻转状态；控制系统与风速仪和驱动系统信号连接，风速仪用于检测风速；驱动系统与隔涡板传动连接，以使隔涡板由初始状态切换至翻转状态。本发明解决了开槽箱梁容易发生显著涡激共振的技术问题。
