Suspension bridge long sling beam end vibration reduction system
The invention discloses a suspension bridge long sling beam end vibration reduction system which comprises a vibration reduction support, a rigid connecting piece and a damper. The vibration reduction support comprises a plurality of supporting columns, curve rigid straining beams and auxiliary connecting rods. The bottoms of the supporting columns are fixed to the main beam, and the multiple supporting columns are annularly arranged around the sling. The curved rigid straining beam is rigidly connected with the end part of the supporting column, the curved rigid straining beam and the supporting column are encircled to form a semi-cylindrical space structure, and a semi-open or full-closed form is adopted; the auxiliary connecting rods are arranged between the supporting columns, and integrity and stability of the support are improved. The rigid connecting piece is rigidly connected with the sling, and a connecting end separated from the rigid connecting piece is connected with the damper; and the damper is arranged between the curve rigid straining beam and the rigid connecting piece and is tightly connected with the curve rigid straining beam and the rigid connecting piece. A formed space structure is stable, attractive in appearance, high in rigidity and small in deformation, a reliable supporting structure can be provided for the damper, meanwhile, an overhaul channel between the sling and a guardrail is not occupied, and operation and maintenance of a bridge are facilitated.
本发明公开了一种悬索桥长吊索梁端减振系统，包括减振支架、刚性连接件、阻尼器；减振支架包括若干支撑柱、曲线刚性系梁和辅助连杆；支撑柱底部固定于主梁，若干支撑柱围绕吊索呈环形布设；曲线刚性系梁与支撑柱端部刚性连接，曲线刚性系梁与支撑柱合围形成半圆柱形空间结构，采用半开口或全闭口形式；辅助连杆设于支撑柱之间，提高支架整体性与稳定性；刚性连接件与吊索刚性连接，且刚性连接件上分出连接端连接阻尼器；阻尼器布设在曲线刚性系梁与刚性连接件之间，与二者紧密连接。本发明形成的空间结构稳定，外形美观、刚度大、变形小，可为阻尼器提供可靠的支撑结构，同时不占用吊索与护栏间的检修通道，有利于桥梁的运营与维护。
