Beam-arch combined body vibration reduction structure and vibration reduction method thereof
The invention relates to the field of bridge seismic resistance, and particularly discloses a beam-arch combined body vibration reduction structure which comprises an upper supporting body, a lower supporting body and a beam-arch combined body, the cylinder body is filled with damping liquid, and a first piezoelectric ceramic sensor in contact with the damping liquid is embedded in the bottom of the cylinder body; the piston is in sliding connection with the cylinder body, a plurality of through holes penetrating through the two ends of the piston are formed in the piston, electromagnetic valves used for controlling the through holes to be opened and closed are arranged in the through holes respectively, and a second piezoelectric ceramic sensor making contact with the damping liquid is embedded in the piston; one end of the piston rod extends into the cylinder body and is fixedly connected with the end of the piston, the other end of the piston rod is fixed to the upper supporting body, and the two ends of the first strain gauge are fixed to the piston rod and the upper supporting body respectively. By means of the technical scheme, normal load and abnormal load can be effectively distinguished, the pulling force on the bridge abutment can be adjusted according to the actual situation, and the damping force can be adjusted according to the viscosity of the damping liquid.
本发明涉及桥梁抗震领域，具体公开了一种梁拱组合体减振结构，包括：上支撑体，上支撑体的下表面嵌入有第一应变片；缸体，缸体内填充有阻尼液，所述缸体底部嵌入有与阻尼液接触的第一压电陶瓷传感器；活塞，活塞与缸体滑动连接，活塞上开设有若干贯穿活塞两端的通孔，所述通孔内分别设有用于控制通孔启闭的电磁阀，所述活塞上嵌入有与阻尼液接触的第二压电陶瓷传感器；活塞杆，活塞杆的一端伸入缸体内，并与活塞的端部固定连接，活塞杆的另一端与上支撑体固定，第一应变片的两端分别与活塞杆和上支撑体固定。采用本发明的技术方案能够有效区分正常荷载和异常荷载，能够根据实际情况调节对桥台拉力，并且根据阻尼液的黏度调节阻尼力大小。
