Abstract: In this paper，first，novel mechanical principle-based extrusion equipment with axial screw vibration is designed，and the principle of the axial screw vibration is analyzed． Then，according to the theory of envelopes，the mathematical equations of the undulant vibration surface are established，and a 3D model of the extrusion e-quipment is constructed． Moreover，by the force analysis of the vibration parts，a physical model describing the screw vibration is established，and the key parameters are theoretically inferred out． Finally，in ADMAS environ-ment，a dynamic simulation of vibration characteristics of the extrusion equipment is carried out． The results show that the designed extrusion equipment exhibits a simple harmonic vibration waveform with small distortion and high stability，which means that the equipment is feasible and effective．

Key words: axial vibration, extrusion molding, ADAMS, dynamic simulation, vibration characteristic
