Example Embodiment

[0021] Example 1

[0022] An aluminum alloy variable-chamber particle collision damper for pipeline vibration damping comprises a pair of semi-circular cylindrical cavities 1 , each of which is provided with a semi-circular outer surface of the cavity surrounding both ends of the cavity. The cover plate 2, the interior of the semi-circular cylindrical cavity 1 is provided with a plurality of cavity internal unit partitions 3, and the multiple cavity internal unit partitions 3 divide the interior of the semi-circular cylindrical cavity 1 into multiple An independent small cavity filled with metal particles 4 . The metal particles 4 inside the cavity will collide and rub against each other as the pipeline vibrates, thereby consuming the vibration energy of the system. The filling rate of the metal particles 4 in the cavity is the main factor affecting the vibration reduction effect of the pipeline. The invention patent has simple structure, small installation space and remarkab...

Abstract

The invention belongs to the technical field of vibration control, and particularly relates to an aluminum alloy variable chamber particle collision damper for pipeline vibration reduction. The dampercomprises a pair of semi-circular ring column cavities, semi-circular ring cavity outer surface cover plates are arranged at the two ends of each semi-circular ring column cavity, a plurality of cavity inner unit partition plates are arranged inside each semi-circular ring column cavity, the plurality of cavity inner unit partition plates divide the interior of each semi-circular ring column cavity into a plurality of independent small cavities, and metal particles filled the small cavities. The metal particles inside the cavities can collide and rub against with one another along with a pipeline vibrated, so that the vibration energy of the system is consumed, wherein the filling rate of the metal particles inside the cavities is the main factor of affecting the vibration reduction effect of the pipeline. The damper is simple in structure, small in mounting space and remarkable in vibration reduction effect.

Description

technical field [0001] The invention belongs to the technical field of vibration control, in particular to an aluminum alloy variable chamber particle collision damper used for pipeline vibration reduction. technical background [0002] In engineering practice, frequent mechanical failures caused by the vibration of the piping system lead to many unsafe incidents. In design practice, pipeline resonance is generally avoided or suppressed by changing the pipeline shape or applying clamps, but there are certain limitations in the specific implementation process. However, most shock absorbers designed based on damping technology and anti-resonance technology have disadvantages such as large mass, limited installation conditions, and poor vibration control effects. [0003] Existing patent applications such as the patent number CN201510613313.9, the application date is 2015.09.24, the invention patent named "Nonlinear particle collision damper", the technical solution is: the in...
