In order to solve the problems of low processing efficiency,poor surface quality and periodic polishing texture in the tra-ditional polishing technology and machine tools,based on the theory of flexible mechanism,a 2D vibration assisted device was designed by means of central symmetry.Based on the flexibility matrix method,the theoretical model of 2D vibration assisted device was estab-lished.The performance test and finite element simulation of the 2D vibration assisted device were carried out.The results show that the maximum stroke of the device is about 46 μm,and the amplification ratio is about 1.21,the natural frequency is about 933 Hz,the cou-pling error rate is about 2.5%,the maximum stress does not exceed 83 MPa,the input stiffness is 23.52 N/μm and the output stiffness is 12.29 N/μm.Through the vibration assisted machining experiment and finite element simulation,it is proved that the vibration assis-ted polishing device has the ability to improve the actual polishing effect.
