摘要

In this paper, the theoretical models of the surface topography and residual stress (RS) were proposed, and the abrasive water jet sequential peening (AWJSP) finite element models were established by using ABAQUS. Then, the formation mechanism of the surface topography in multiple passes AWJSP process and the coupling mechanism of RS in a single and multiple passes AWJSP process were analyzed. After that, the influence of the number of shots (i.e. N ), the distance between the center of adjacent shots D_(c) , shot velocity v , and shot radius R on the surface topography and residual stress field (RSF) of the target were investigated. Results show that successive dimples were formed by single-pass AWJSP, the RSF formed by the impact of each shot will influence the previous RSF, and that will be coupled with it. In multiple passes AWJSP process, decreasing D_(c) can decrease the surface roughness, the surface smoothness of the target material will gradually become better, and the RSF will also be uniform. Under full coverage condition, the surface roughness R_(t) and mean width of the profile R_(sm) will gradually decrease with the decrease of D_(c) , while the change of D_(c) has little influence on the RSF. Increasing the v can increase R_(t) and R_(sm) , and it is beneficial to induce a large and deep compressive RS layer. Increasing the R can decrease R_(t) , R_(sm) remains unchanged, and it is beneficial to induce a deep compressive RS layer.
