| 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. |

| Keywords: | frequency response function (FRF) scroll compressor water-cooled chiller frame vibration suppression |
