Staged variable-stiffness viscous damper and mounting method and application thereof
The invention belongs to the field of bridge seismic mitigation and isolation, and discloses a staged variable-stiffness viscous damper and an installation method and application thereof.The staged variable-stiffness viscous damper comprises an outer cylinder body and two inner cylinder bodies arranged in the outer cylinder body, pistons are arranged in the two inner cylinder bodies respectively, piston rods penetrate into the outer cylinder body and are connected with the pistons, and the piston rods are connected with the outer cylinder body. A group of dowel bars are uniformly arranged on the piston rod in the circumferential direction, friction blocks are connected to the two ends of each dowel bar, a base plate is mounted on the inner cylinder body close to the end part of the outer cylinder body through a bayonet lock, a first spring group is arranged between the friction blocks and the base plate, and a second spring group is arranged at the end parts of the inner cylinder body and the outer cylinder body; a friction damping module is further arranged between the outer cylinder body and the inner cylinder body. The problems that a traditional damper is insufficient in energy dissipation capacity and short in service life are solved through dual synergy of a friction damping energy dissipation mechanism and a viscous damping energy dissipation mechanism, and the energy dissipation efficiency and durability of the damper are improved.
本发明属于桥梁减隔震领域，公开了一种分阶段变刚度粘滞阻尼器及其安装方法及应用，该分阶段变刚度粘滞阻尼器包括外缸体以及设置在外缸体里面的两个内缸体，两个内缸体里面分别设置有活塞，活塞杆穿入外缸体并与活塞连接，活塞杆上预制有构造圆盘，构造圆盘的圆周方向均匀设置有一组传力杆，传力杆的两端连接有摩擦块，内缸体上靠近外缸体端部通过卡销安装有垫板，摩擦块与垫板之间设置有第一弹簧组，内缸体与外缸体的端部设置有第二弹簧组，外缸体与内缸体之间还设置有摩擦阻尼模块。本发明采用摩擦阻尼与粘滞阻尼耗能机制双重增效解决了传统阻尼器耗能能力不足与寿命短的问题，提升阻尼器的耗能效率与耐久性。
