Limiting damper with variable inerter
The invention relates to a limiting damper with a variable inerter. The limiting damper with variable inerter comprises fixed supports, a piston, wavy mild steel buffering and limiting devices and a hydraulic cylinder, wherein the fixed supports are mounted on a damping structure, the piston is mounted in the middle of the two fixed supports, and a magnetorheological fluid hydraulic cylinder is mounted in the middle of the piston; the hydraulic cylinder is filled with magnetorheological fluid, the inner wall of a container is provided with an electromagnetic coil, two circles of outer spiral pipelines with different section diameters are wound on the outer wall of the container, and a switch valve is arranged between the outer spiral pipelines and the container, and the wavy mild steel buffering and limiting device is mounted on the fixed supports correspondingly. According to the device, the inerter of the inerter can be adjusted, so that an efficient damping effect is generated for different power inputs, and the wavy mild steel buffering and limiting devices mounted on the fixed supports can work together with the hydraulic cylinder when a large displacement is generated by thedamping structure to form a multi-level energy dissipation combination, and the structure can be prevented from generating a larger displacement.
本发明涉及一种具有可变惯容的限位阻尼器，包括固定支座，活塞，波浪形软钢缓冲限位装置、液缸，所述固定支座安装在减震结构上，活塞安装在两个固定支座中间，磁流变液液缸安装在活塞中部；所述液缸内充满磁流变液，容器内壁安装有电磁线圈，容器外壁绕有两圈截面直径不等的外螺旋管道，所述外螺旋管道与容器间有开关阀；所述波浪形软钢缓冲限位装置安装在固定支座上。该装置可实现惯容器的惯容可调，从而针对不同的动力输入产生高效的阻尼效果，安装在固定支座上的波浪形软钢缓冲限位装置可在减震结构产生较大的位移时与液缸共同工作，形成多级耗能组合，并避免结构产生更大的位移。
