Sectional variable damping viscous damper controlled by force
The invention relates to the technical field of vibration and shock resistance of bridges, in particular to a force-controlled segmented variable-damping viscous damper which comprises a left spherical hinge seat, a plug component, a cylinder body, a piston rod, a right spherical hinge seat, a damping medium and a piston assembly. The piston rod is arranged in the cylinder body, one end of the piston rod is connected with the left spherical hinge base, one end of the cylinder body is movably connected with the left spherical hinge base, and the other end of the cylinder body is movably connected with the right spherical hinge base. The two sides of the cylinder body are connected with the piston rod through plug components to form a sealing cavity, damping media are contained in the sealing cavity, and a piston assembly which is arranged on the outer side of the piston rod in a sleeving mode and used for adjusting the damping coefficient and the damping index is arranged in the middle of the sealing cavity. The force-controlled segmented variable-damping viscous damper is simple in structure, convenient to debug and low in cost increase, can meet the vibration reduction requirements of a bridge in various operation states, and has a good application prospect.
本发明涉及桥梁的抗减振抗震技术领域，尤其是涉及一种用力控制的分段变阻尼黏滞阻尼器，包括左球铰座、堵部件、缸体、活塞杆、右球铰座、阻尼介质和活塞组件；活塞杆设置于缸体内部，一个端部与左球铰座相连接，缸体一个端部与左球铰座活动连接，另一个端部与右球铰座活动连接；缸体的两侧通过堵部件与活塞杆相连接以形成密封腔体，密封腔体内容纳有阻尼介质，密封腔体中部设置有套设于活塞杆外侧的用于调整阻尼系数和阻尼指数的活塞组件。本发明的用力控制的分段变阻尼黏滞阻尼器结构简单、调试方便，成本增加少，能够满足桥梁在多种运行状态下的减振要求，具有较好的应用前景。
