Variable-stiffness nonlinear energy collection and vibration suppression device
The invention relates to a variable-stiffness nonlinear energy collection and vibration suppression device. According to the variable-stiffness nonlinear energy collection and vibration suppression device, gear mass blocks are connected with energy dissipation dampers through springs, and the inner gear mass block and the outer gear mass block of the variable-stiffness nonlinear energy collection and vibration suppression device are connected through two semicircular cylinders through bolt connecting pieces. Eight pinions connected with the energy-consuming dampers through springs are arranged in the middle, every two pinions form a group, four groups of gears are arranged, and one pinion in each group is meshed with an internal gear (the gear connected with a cable or a suspender) and the other pinion in each group is meshed with an external large gear. A coil is arranged in the middle of the waist portion of the internal gear, a magnetic block is arranged in the middle of the waist portion of the external large gear, when a cable vibrates, the vibration amplitude of the cable is restrained through a mass block of the variable-rigidity nonlinear energy collection and vibration restraining device, and generated energy is consumed by cutting magnetic induction lines through the coil to generate electric energy. The device can be used for reducing the vibration amplitude of the cable or the suspender under the action of wind load, vehicle load and the like, so that the driving comfort of a bridge is improved, and the service life of the bridge is prolonged.
本发明涉及一种变刚度非线性能量采集与振动抑制装置。一种变刚度非线性能量采集与振动抑制装置由齿轮质量块通过弹簧与耗能阻尼连接，一种变刚度非线性能量采集与振动抑制装置内外两个齿轮质量块由两个半圆环的柱体通过螺栓连接件连接，中间有八个通过弹簧与耗能阻尼连接的小齿轮，小齿轮两个一组，一共四组齿轮，每组小齿轮一个啮合在内部齿轮上(与索或吊杆连接的齿轮)另一个则啮合在外部大齿轮上。内部齿轮腰部中间布置线圈，外部大齿轮腰部中间布置磁块，当索振动时由一种变刚度非线性能量采集与振动抑制装置本身的质量块抑制索的振幅，产生的能量由线圈切割磁感线产生电能消耗掉。本发明可用于减少索或吊杆在风荷载、车辆荷载等作用下的振动摆幅，从提高桥梁的行车舒适度以及桥梁寿命。
