Analysis of Vibration Suppression Effectiveness on Frames of Water-cooled Chillers

Abstract

Abstract: A vibration suspend frame was designed according to the structural characteristics of the chiller,and the natural frequencies and modes were calculated by ANSYS software.An evaluation method for vibration suppression effectiveness on the chiller frames was presented using FRF.The FRF was obtained through simulation method by ANSYS software,and the feasibility of the method was verified by experiments.The results show that the designed frame has an obvious vibration suppression effectiveness,and the FRF method may effectively evaluate the vibration suppression effectiveness of the units or components.

Key words: frequency response function (FRF), scroll compressor, water-cooled chiller, frame, vibration suppression

摘要： 根据冷水机组结构特性设计了一种减振机架,并利用ANSYS对其固有频率和模态进行了计算；提出了一种利用频响函数法对冷水机组机架的减振效果进行评估的方法,通过ANSYS仿真得到了其频响函数,最后通过实验验证了该方法的可行性。结果表明,该机架具有明显的减振效果,频响函数法可以有效地评估机组或部件的减振效果。
