摘要

针对离心式空调冷水机组在300Hz和386Hz工况下的振动，提出了一种基于粒子阻尼的离心式空调冷水机组减振方法。首先，在分析冷水机组动态特性的基础上，确定了冷水机组的振动传递路径;其次，通过有限元分析确定了压缩机的振动敏感区域;然后利用离散元法(DEM)计算耗能，确定阻尼器的最佳安装方案。最后，通过实验验证了设置阻尼器后冷水机组的减振效果。

Research on optimal design of vibration reduction of centrifugal air conditioning chiller based on particle damping

Considering vibration of centrifugal air-conditioning chillers at working conditions of 300Hz and 386Hz, a vibration reduction method for centrifugal air-conditioning chillers based on particle damping is proposed. Firstly, the vibration transfer path of the chillers is determined based on dynamic characteristics analysis of the chillers. Secondly, the vibration sensitive area of the compressor is determined by ﬁnite element analysis. Then the energy dissipation is calculated by the discrete element method (DEM) to determine the optimal installation scheme of the damper. Finally, the vibration reduction eﬀect of the chillers after arranging the damper is veriﬁed by experiments.
