The invention provides a tandem type variable-damping viscous fluid damper. The tandem type variable-damping viscous fluid damper comprises a main cylinder barrel, an auxiliary cylinder barrel, a piston rod and a main piston fixedly arranged on the piston rod in a sleeving manner, the main cylinder barrel is connected with the auxiliary cylinder barrel, the piston rod is located in the main cylinder barrel and the auxiliary cylinder barrel and can do reciprocating motion in the axial direction of the main cylinder barrel, and the main piston is located in the main cylinder barrel; a secondarycylinder barrel is further arranged between the main cylinder barrel and the auxiliary cylinder barrel, a secondary piston fixedly installed on the piston rod in a sleeving manner is arranged in the secondary cylinder barrel, a gap is formed between the inner wall of the secondary cylinder barrel and the outer wall of the secondary piston, the inner wall of the secondary cylinder barrel is a curvein the axial direction, the gap changes along with changes of the inner wall of the secondary cylinder barrel, and the minimum inner diameter of the secondary cylinder barrel is equal to the outer diameter of the secondary piston; and damping holes are formed in the main piston and the secondary piston in the axial direction, and the secondary cylinder barrel and the main cylinder barrel are filled with damping media. According to the viscous fluid damper, the requirement for variable damping is decomposed into superposition of two common viscous fluid dampers, the viscous fluid damper is designed on the basis of the common viscous fluid dampers, and the design cost, the machining cost and the performance test cost are saved.
本发明提出了一种串联式变阻尼黏滞流体阻尼器，包括主缸筒、副缸筒、活塞杆和固定套装在活塞杆上的主活塞，所述主缸筒与副缸筒相连，活塞杆位于主缸筒和副缸筒内且可沿主缸筒轴向往复运动，主活塞位于主缸筒内，所述主缸筒以及副缸筒之间还设置有次缸筒，次缸筒内设置有固定套装在活塞杆上的次活塞，次缸筒内壁与次活塞外壁形成间隙，所述次缸筒内壁沿轴向呈现为曲线，间隙随次缸筒内壁变化而变化，次缸筒最小内径等于次活塞外径；所述主活塞和次活塞上均沿轴向开设有阻尼孔，次缸筒和主缸筒内填充有阻尼介质。本发明将变阻尼的要求分解为两个普通黏滞流体阻尼器的叠加，在普通黏滞流体阻尼器的基础上设计，节约了设计、加工与性能试验的成本。
