Influence of Ultrasonic Vibration on Metal Plastic Forming

Establish the ultrasonic single-point extrusion experiment platform to carry out the experiment of conventional extrusion and ultrasonic extrusion for different materials. Compared with experimental results, explore volume effect of ultrasonic vibration plastic forming and analyze the impact of different amplitude of ultrasonic resonance on material's plastic deformation volume. It can be found that ultrasonic vibration has an influence on stress-strain of material to a certain extent. Take advantage of the MSC.Marc finite element simulation software to continually modify the stress-strain curves of the material, finally the simulation result coincides with experimental conclusion. The results show that ultrasonic vibration has a significant impact on metal forming, improving the flowing property of metallic material processing, and softening materials, which further proves that ultrasonic vibration has great effects and provides the theoretical basis for it in material of plastic processing application.
