摘　　要：针对国内某1000 kt/a乙烯项目丙烯制冷压缩机出口管线振动过大的问题,研究了粒子阻尼减振技术在管道上的减振效果。采用有限元分析方法进行了模态分析及阻尼减振仿真计算,结合现场测试数据,分析了管线振动的原因,结合现场的空间布置参数及理论计算结果,设计了合理的管道阻尼减振方案,在原始管线结构不改变、相关设备不停机的情况下,结合现场空间尺寸,完成了阻尼减振器的现场安装,有效地限制管线的振动在安全范围内,确保了装置设备的安全运行。Aiming at the problem of excessive vibration in the outlet pipeline of the propylene refrigeration compressor of a domestic 1 million t/a ethylene project,this paper studies the vibration reduction effect of particle damping technology on the pipeline.The modal analysis and damping vibration reduction simulation calculation were carried out by using the finite element analysis method.Based on the field test data,the causes of pipeline vibration were analyzed.And then combined with the field layout parameters and theoretical calculation results,a reasonable scheme for damping vibration reduction of pipeline was designed.The on-site installation of the damping shock absorber was completed without changing the original pipeline structure and shutting down the related equipment combining with the site space size.This effectively reduced the vibration of the vibrating pipeline to a safe range and ensured the safe operation of the equipment.
