Particle damping dynamic vibration absorber for pipeline

The invention discloses a particle damping dynamic vibration absorber for a pipeline. Comprising a pair of vibration absorber shells, damping particle shells arranged in the vibration absorber shells, damping particles arranged in the damping particle shells, elastic pieces arranged between the damping particle shells and the vibration absorber shells, and rolling pieces arranged between the inner wall faces of the vibration absorber shells and the outer wall faces of the damping particle shells. The pair of vibration absorber shells is in butt joint to form an assembly hole for a pipeline to pass through. According to the particle damping dynamic vibration absorber for the pipeline, the rigidity of the elastic piece and the mass of the damping particle shell and the damping particles are adjusted, so that the first-order inherent frequency of a vibrator formed by the damping particle shell and the damping particles is equal to the main vibration frequency of the pipeline, and therefore vibration energy of th
