Displacement amplification type bridge damping energy consumption device with self-resetting limiting function
The invention relates to a displacement amplification type bridge damping energy consumption device with a self-resetting limiting function. The displacement amplification type bridge damping energy consumption device comprises a hydraulic displacement amplification system and an SMA inhaul cable system. The hydraulic displacement amplification system is composed of a connecting rod, a hydraulic displacement amplifier, a damping medium and related accessories, the hydraulic displacement amplifier achieves displacement amplification of the connecting rod through piston cylinders with different sectional areas, and connecting rod pistons can only move in respective cylinders to achieve the limiting function; the SMA inhaul cable system is composed of a check block, end plates, an ejector rod, an SMA inhaul cable and related accessories, the SMA inhaul cable tensions the first end plate and the second end plate, the first end plate and the second end plate are stopped by the check block from getting close to each other, the ejector rod with the displacement adjusted through the hydraulic displacement amplification system can push the end plates with the opposite movement directions to move in the positive direction and the negative direction, the first end plate and the second end plate are made to be far away, and the hydraulic displacement amplification system is used for amplifying hydraulic displacement. And the self-resetting capability is provided by the SMA inhaul cable. The size of the device can be reduced, a self-resetting limiting function and a displacement amplification function are provided, and the energy dissipation capacity of the device is improved.
本发明涉及一种具有自复位限位功能的位移放大型桥梁减震耗能装置，包括液压位移放大系统和SMA拉索系统；液压位移放大系统由连杆、液压位移放大器、阻尼介质及相关配件组成，液压位移放大器通过截面积不同的活塞缸实现连杆位移放大，连杆活塞只能在各自筒体内运动，实现限位功能；SMA拉索系统由挡块、端板、顶杆、SMA拉索及相关配件组成，SMA拉索将第一端板、第二端板拉紧，第一端板、第二端板由挡块阻挡其相互靠近，经液压位移放大系统调整位移后的顶杆在正反方向均可推动运动方向正对的端板移动，使第一端板、第二端板远离，由SMA拉索提供自复位能力。本发明可缩小装置尺寸，提供自复位限位功能和位移放大功能，提升装置耗能能力。
