Positive pressure adjustable type barrel-shaped friction damper
The invention discloses a positive pressure adjustable type barrel-shaped friction damper, and belongs to the technical field of structure damping. A piston outer tube and a friction assembly generatefriction force, so that the vibration amplitude of a structure can be quickly replaced, and input vibration energy is consumed. A piston inner tube and the piston outer tube are arranged inside an inner barrel, the friction assembly is fixed on the middle part of the inner barrel, and covers the piston outer tube; the piston outer tube is provided with two axial opening seams; after the piston inner tube with a variable-section shape is screwed into the piston outer tube, the piston outer tube is opened outwards, so that positive pressure between the piston outer tube and the friction assembly is increased; and while the friction damper generates relative displacement, the piston outer tube and the friction assembly mutually rub to generate stable and reliable friction force, so that theeffects of isolating vibrations and damping are achieved better. The positive pressure adjustable type barrel-shaped friction damper disclosed by the invention is simple in structure, can perform pressure intensity regulation, can prefabricate and process parts and fittings in a plant, can guarantee hysteretic curves of the parts and the fittings to be stable, is better in damping protection effect, is high in safety coefficient, is high in structure durability, and can be used for a long time.
本发明公开了一种正压力可调式筒型摩擦阻尼器，属于结构减震技术领域。活塞外管与摩擦组件产生摩擦力，可快速降低结构振动幅度，消耗输入振动能量。内筒内部设置有活塞内管和活塞外管，摩擦组件固定于内筒中部，且包裹住活塞外管，活塞外管有两条轴向开缝，变截面形状的活塞内管旋入活塞外管后，将活塞外管往外撑开，使得活塞外管与摩擦组件的正压力增大，当摩擦阻尼器发生相对位移，活塞外管与摩擦组件相互摩擦，产生稳定可靠的摩擦力，更好地起到隔震减震的作用。本发明结构简单，可进行压强调节，各零部件和配件均可在工厂预制加工，可保证其滞回曲线稳定，减震的防护效果更好，安全系数高，结构耐久性高，可长期使用。
