Self-resetting and variable-rigidity composite damper
The invention relates to a self-resetting and variable-rigidity composite damper. The self-resetting and variable-rigidity composite damper comprises a railcar group formed by connecting a plurality of railcars in series as well as a magnetorheological damper; the railcars are arranged on sliding rails arranged on a damping structure; the two ends of the railcar group are connected with the damping structure through the magnetorheological damper; the adjacent railcars are connected through an energy-consuming connecting assembly; a cavity is formed in each railcar; a movable magnetic isolatingsliding sheet is arranged in the cavity; a rubber coated steel ball is arranged between the cavity and the magnetic isolating sliding sheet; and a locking mechanism for fixing the magnetic isolatingsliding sheet is arranged at one end, far away from the rubber coated steel ball, of the cavity. In the face of small wind and small vibration, vibration absorption and energy consumption are conducted by a spiral spring, the magnetorheological damper and an SMA pull rope; and the rubber coated steel balls move and collide in the railcars to consume energy.
本发明涉及一种自复位的变刚度复合阻尼器，包括由若干个有轨车串联组成的有轨车组，以及磁流变阻尼器，所述有轨车安装在设于减震结构上的滑轨上，所述有轨车组的两端通过所述磁流变阻尼器与减震结构相连接，相邻有轨车之间通过耗能连接组件相连接；所述有轨车内设有腔体，所述腔体内设有能够移动的磁性隔离滑片，所述腔体与磁性隔离滑片之间设有橡胶外包钢球，所述腔体在远离所述橡胶外包钢球的一端设有用于将磁性隔离滑片固定的锁定机构。面对小风、小震时利用螺旋弹簧、磁流变阻尼器、SMA拉索进行吸振耗能；通过橡胶外包钢球在有轨车中运动、碰撞进行耗能。
