Abstract：The pressure gauge on the crude oil pipeline vibrates greatly and the pointer swings back and forth, resulting in inaccurate pressure readings. In response to the above issues, this paper adopted particle damping technology to conduct vibration reduction research on the pressure gauge and the thin tube below. The collision energy dissipation mechanism of damping particles was explored in this paper. Based on the results of collision energy dissipation and friction energy dissipation in theoretical analysis, copper particles with explosion-proof function and significant vibration reduction effect were selected as the damper particles. Moreover, a damper which can be installed on thin pipes with a diameter of 15mm was designed. After installing the particle damper, the vibration reduction effect of the thin tube reaches 38%.
