Mass-tuned damping particle composite type built-in vibration reduction device
The invention discloses a damping particle composite type built-in vibration reduction device with tuned mass. The device is pre-buried and installed in a force bearing structure below a steel rail. The device comprises a box body shell, a spring and a mass tuning container are arranged in the box body shell, a plurality of baffles are arranged in the mass tuning container, the mass tuning container is divided into a plurality of independent cavities by the baffles, and the cavities are closed containers and are filled with damping particles; vibration energy is consumed through collision and friction between the damping particles and the inner wall of the cavity and mutual collision and friction between the damping particles. The spring is arranged between the mass tuning container and the box body shell, so that the energy consumption efficiency is improved, and the mass tuning container can be protected; according to the device, the movement distance and the kinetic energy of the particle units are increased by utilizing the displacement and the acceleration of the mass tuning container, the energy consumption is increased, the vibration and noise reduction means are enriched and increased, and a good economic effect can be achieved.
本发明公开了一种质量调谐的阻尼颗粒复合型内置减振装置，该装置预埋安装在钢轨下方的承力结构中；该装置包括箱体外壳，在箱体外壳内部设置有弹簧和质量调谐容器，在该质量调谐容器内部设置有多块挡板，所述挡板将所述质量调谐容器分割为多个彼此独立的空腔，所述空腔为密闭容器，其内填充有阻尼颗粒；通过阻尼颗粒与空腔内壁碰撞及摩擦、阻尼颗粒之间相互碰撞及摩擦来消耗振动能量；所述弹簧设置在质量调谐容器与箱体外壳之间，提高耗能效率，还能够保护质量调谐容器；该装置利用质量调谐容器的位移及其加速度的作用，加大颗粒单元的运动距离和动能，加大能量消耗，丰富和增加减振降噪的手段，并能取得良好的经济效果。
