Since a surface effect is of complexity for drawing process with pulse vibration,a dynamic differential equation was built by mechanics analyzed for cell body in drawing die and combined with the Fourier transform.On the basis of the non-local friction theorem,some non-local infection coefficients concerning with friction were computed,and the linearity strengthened model was used for searching approximate resolution,then dynamic friction model for pulse vibration drawing was obtained on non-local condition.According to metal material mechanical performance parameters,drawing process parameters,vibration parameters and the non-local infection coefficients were given.The simulation by MATLAB shows that the surface effect of pulse vibration drawing mainly relates with vibration parameters,and its surface effect appearing during drawing process is more superior than that of the other vibration.These results can provide important guidance for vibration available used.
