Built-in compartment type particle inertial-capacitance damper
The invention discloses a built-in compartment type particle inertial-capacitance damper. The built-in compartment type particle inertial-capacitance damper is characterized in that one end of a ballscrew is inserted into a first metal shell through a nut, and the other end of the ball screw is inserted into a second metal shell through a bearing and welded to a flywheel; a plurality of compartments are arranged in the flywheel, the areas of the compartments are the same or different, a certain number of particles are placed in the compartments, the particle filling rates are the same or different, and thus the multi-frequency tuning function is achieved; and energy dissipation layers are attached to the inner walls of the compartments. When a controlled component vibrates to enable the first metal shell and the second metal shell to move relatively, the ball screw can drive the flywheel to rotate to generate inertial force, and vibration energy is absorbed; and the particles in the compartments of the flywheel move along with the flywheel and collide and rub with other particles and the energy dissipation layers to consume energy of the particles, and thus the purpose of energy dissipation is achieved. The built-in compartment type particle inertial-capacitance damper has the multiple functions of inertial-capacitance energy absorption, friction energy dissipation, multi-frequency tuning and the like, and vibration between structures under the effects of wind loads, earthquakes, blasting impact and the like can be effectively reduced.
本发明公开了一种内置隔舱式颗粒惯容阻尼器，包括滚珠丝杠一端通过螺母插入金属外壳一内，另一端通过轴承插入金属外壳二内，并与飞轮焊接在一起；飞轮内部设置若干隔舱，隔舱面积相同或不同，并放置一定数量的颗粒，颗粒填充率相同或不同，以此实现多频调谐的功能，隔舱内壁贴合耗能层。当受控构件振动使得金属外壳一与金属外壳之间发生相对运动时时，滚珠丝杠会带动飞轮转动产生惯性力，吸收振动能量；飞轮隔舱内的颗粒随着飞轮运动，并与其他颗粒以及耗能层发生碰撞、摩擦消耗自身能量，从而达到耗能的目的。本发明兼具惯容吸能、摩擦耗能和多频调谐等多重功能，可有效减小风荷载、地震以及爆破冲击等作用下结构之间的振动。
