Metal damper for bridge shock absorption and energy consumption
The invention belongs to the technical field of dampers, and particularly relates to a metal damper for bridge shock absorption and energy consumption. The device structurally comprises a left connecting body, a right connecting body and a plastic deformation steel frame arranged between the left connecting body and the right connecting body, the left connecting body is connected with the bottom face of a bridge, the right connecting body is connected with the top face of a pier, the plastic deformation steel frame comprises one or more damping units, and each damping unit is formed by symmetrically arranging two U-shaped rods; two supporting legs of the U-shaped rod are movably connected with the left connecting body and the right connecting body respectively, and the U-shaped rod is made of elastic-plastic steel. The novel metal damper has the advantages of being convenient to mount and dismount, excellent in bridge damping and energy dissipation performance, simple and compact in structure and good in use durability.
本发明属于阻尼器技术领域，具体的讲涉及一种用于桥梁减震耗能的金属阻尼器。其结构包括左联结体、右联结体以及设置在二者之间的塑性变形钢架，其中，左联结体与桥梁底面连接，右联结体与桥墩顶面连接，塑性变形钢架包括一个或多个阻尼单元，阻尼单元由两个U型棒对称布置构成，U型棒的两个支脚分别与左联结体、右联结体活动连接，U型棒由弹塑性钢制成。该新型金属阻尼器便于安装和拆卸、对桥梁减震耗能性能优越且结构简单紧凑、使用耐久度好的特点。
