Vibration absorber design of loom has been researched in this paper. Dynamic model of structure system of loom has been established, and the imitated process forces were forced on the model. Design and parameters optimizing of vibration absorber were made by computer simulation technique. Optimized parameters of the isolator have been gained by the ANSYS software which the rigidity on uprightness orientation is 25.1×10^4 N/re,and the damp on uprightness orientation is 6273 N·s/re.The vibration response of loom was simulated. The result of experiment explicated that the dynamic response of structure system and the efficiency of vibration insulation had achieved design requirement.
