Viscous damper with variable damping strength and method
The invention discloses a viscous damper with variable damping strength and a method. The viscous damper comprises a cylinder barrel, damping liquid sealed in the cylinder barrel, a piston rod arranged in the cylinder barrel, a middle damping piston, two end pistons and two reset elastic pieces. The piston rod moves towards one end, the middle piston connected with the piston rod also moves along with the piston rod, and at the moment, damping force is generated by movement of viscous media in a gap between the middle piston and the cylinder barrel. When the middle piston is in contact with the end pistons, the middle piston and the end pistons move together, equivalently, the width of the pistons is increased, viscous media between the pistons and the cylinder barrel are increased, damping force generated by motion of the viscous media is increased, and meanwhile the springs are compressed by the pistons, spring elasticity is added, and the damping force is further increased. And during returning, the reset elastic piece can push the end piston to move and return to the initial position, the damping force can be adjusted in a self-adaptive mode according to the actual stress degree, the overall structure is stable, reliable and safe, and the multi-stage self-adaptive adjusting effect of the damping force is achieved.
本发明公开了一种阻尼强度可变的黏滞阻尼器和方法，包括缸筒，密封在缸筒内的阻尼液，和置于缸筒内的活塞杆、中置阻尼活塞、两个端部活塞以及两个复位弹性件；活塞杆向一端运动，与活塞杆相连中间活塞也随之运动，此时阻尼力是由中间活塞与缸筒之间间隙的黏滞介质运动产生的。当中间活塞与端部活塞接触后，两者一起运动，相当于活塞宽度增加，与缸筒之间黏滞介质增加，黏滞介质运动产生的阻尼力增大，同时活塞压缩弹簧，附加弹簧弹力，阻尼力进一步增大。返回时，复位弹性件能推动端部活塞运动，回到初始位置，具有能自适应根据实际受力程度调整阻尼力，且整体结构稳定可靠安全，实现了阻尼力的多级自适应调节效果。
