Abstract: Compared with traditional passive vibration reduction, damping vibration control has high stability and superior controllability. It can convert mechanical vibration energy into other energy dissipation which can achieve the purpose of vibration reduction. In order to solve the vibration problem of outlet pipelines of Rich Gas Compressor in a petrochemical company in Shandong. The finite element analysis software ANSYS combined with on-site vibration situation was used to find out the cause of the pipeline vibration. The feasibility of damping vibration control was analyzed by reduction principle. And the SAP2000 was used to simulate the damping vibration control effect in which the further optimize solution was proposed. By using damping vibration control technology, combined with on-site arrangement of pipeline, without stopping the compressor and changing the pipeline structure, the dampers were installed. After the installation, the outlet pipeline vibration was reduced by more than 60% which made the whole system in a safe range of Purdue vibration standard, and the maximum drop is 94.2%. Furthermore the security risk was eliminated and the pipeline system was able to operate safety. Besides, the vibration reduction of the whole platform is over 60% which proved the damping vibration control is beneficial to the stability of chemical equipment platform.
