摘　　要：黏滞性阻尼器是一种速度相关型阻尼器,阻尼器的阻尼介质在缸筒里流动,通过活塞孔的时候,经过活塞上的特定孔隙形成阻尼力,产生阻尼效果并以分子热能的方式耗散载荷输入能量,达到阻尼耗能的目的。文中通过对黏滞性阻尼器的性能设计、结构设计、试验校核等,最终确定阻尼器的设计研究方法,另外,对阻尼器速度的控制是通过对溢流阀的调整来实现的。Viscous damper is a velocity dependent damper.The damping medium of the damper flows in the cylinder.When passing through the piston hole,it forms a damping force through the specific hole on the piston to produce a damping effect,and dissipates the load input energy in the form of molecular heat energy to achieve the purpose of damping energy consumption.Through the performance design,structural design and test verification of viscous damper,the design and research method of damper is finally determined.In addition,the speed control of damper is realized by adjusting the overflow valve.
