Magneto-rheological pipeline dual-dynamic damping absorber

The invention discloses a magneto-rheological pipeline dual-dynamic damping absorber. The mode of combining dynamic vibration absorption and damping dissipation energy vibration damping is adopted for controlling vibration of a pipeline. A magneto-rheological damper is adopted as a mass block and a leaf spring to form a first-order dynamic vibration damping structure, when the pipeline vibrates, the mass block and the leaf spring vibrate along with the pipeline and generate inertia reactive force, and vibration of the pipeline is lowered. A piston body, a spring, magneto-rheological fluid and a cylinder tube of the magneto-rheological damper form a second-order dynamic damping vibration damping structure. When the magneto-rheological damper vibrates along with the pipeline, the piston body compresses the piston to generate reactive force for the magneto-rheological damper under the inertia effect, and when the piston body and the cylinder tube move relatively, the piston body dissipates vibration energy under
