Novel negative stiffness inerter particle damper
The invention discloses a novel negative stiffness inerter particle damper, and belongs to the technical field of vibration attenuation and damping. Comprising an outer cavity, a roller is installed in the center of the interior of the outer cavity, a gear and rack assembly fixed through a fixing shaft is arranged in the roller, the two ends of the gear and rack assembly are connected with connecting pieces, and the gear and rack assembly is connected with a fixing frame arranged on one side of the interior of the outer cavity through a pre-compression spring. According to the invention, the roller is divided into a plurality of independent spaces, so that the problem of particle stacking is avoided, and each particle fully plays a damping role; horizontal motion is converted into rotary motion through the gear and rack assembly, the collision speed and collision force of particles are increased, and the good control effect can be achieved with the small particle mass ratio. Noise generated by particle collision is effectively reduced, and meanwhile the collision energy consumption effect of the particles is improved. Relative movement of two end points of the damper is assisted through the negative stiffness effect, and the energy consumption effect is further improved.
本发明公开了一种新型负刚度惯容颗粒阻尼器，属于减振阻尼技术领域。包括外腔体，外腔体内部中央处安装有滚筒，滚筒内部设置有通过固定轴固定的齿轮齿条组件，齿轮齿条组件两端均与连接件连接，且齿轮齿条组件通过预压缩弹簧与设置在外腔体内部一侧的固定框连接。本发明将滚筒分割为多个独立的空间，避免了颗粒堆叠问题，使每个颗粒都充分发挥减振作用；通过齿轮齿条组件将水平运动转化为旋转运动，放大了颗粒的碰撞速度和碰撞力，能以较小的颗粒质量比实现良好的控制效果。有效降低了颗粒碰撞产生的噪音，同时增加颗粒的碰撞耗能效果。通过负刚度效应来辅助阻尼器两端点的相对运动，进一步提高耗能效果。
