Gear inerter negative stiffness friction damping device
The invention relates to the technical field of structural vibration control, in particular to a gear inerter negative stiffness friction damping device. Comprising a shell, a gear inerter system, a drum brake friction system and a straight rack for jointly driving the gear inerter system and the drum brake friction system, and further comprises a linear bearing and a rack limiter for limiting working planes of the gear inerter system and the drum brake friction system; the gear inerter system comprises a first-stage gear set and a second-stage gear set which are meshed with each other, any gear set comprises two straight gears which are oppositely arranged in a spaced mode and are different in size, the central axes of the two straight gears in each gear set are jointly provided with a transmission shaft, and the transmission shaft is connected through a flat key. Two ends of the transmission shaft are provided with rotating bearings connected with the shell; the drum brake friction system comprises a driving gear and friction round steel concentrically welded with the driving gear, and a drum brake is arranged on the inner side of the friction round steel. Friction damping is generated to dissipate energy while negative stiffness is provided, and the double-control strategy of structural displacement and acceleration is achieved.
本发明涉及结构振动控制技术领域，尤其涉及一种齿轮惯容负刚度摩擦阻尼装置。包括外壳、齿轮惯容系统、鼓刹摩擦系统以及共同驱动齿轮惯容系统和鼓刹摩擦系统的直齿条，还包括有限定齿轮惯容系统和鼓刹摩擦系统工作平面的直线轴承和齿条限位器；所述齿轮惯容系统包括两组相互啮合的一级齿轮组、二级齿轮组，任一齿轮组包括两个相对间隔设置且大小各异的直齿轮，每个齿轮组内的两个直齿轮中心轴线共同设置有一根传动轴并通过平键相连，传动轴两端设置有转动轴承与外壳相连；所述鼓刹摩擦系统包括驱动齿轮和与驱动齿轮同心焊接的摩擦圆钢，摩擦圆钢内侧设有鼓刹器。本发明在提供负刚度的同时产生摩擦阻尼进行耗能，实现结构位移与加速度的双控策略。
