Article Preview

Ultrasonic shot peening can be used to strengthen mechanical parts. Its equipment structure is compact, which is convenient for incorporated into production line. It is fitting to facilitate operation and high reproducibility without dust pollution and noise. The finite element simulation method of ultrasonic shot peening further contributes to the development of ultrasonic shot peening technology. In the present work, finite element simulation method was adopted to establish a three-dimensional numerical model for analyzing the strengthening mechanism of ultrasonic shot peening. By choosing reasonable material model and different combination of parameters (such as treated material, diameter of shots, peening velocity), the curves of residual stress vs. depth of alloy materials were obtained, including the relationships between the peak value and depth of residual compression stress and peening velocity.
