Vibration　stress　relief　(VSR)　and　thermal　stress　relief　(TSR)　are　important　method　to　eliminate　the　residual　stress　of　structural　parts.　The　thermal-vibratory　stress　relief　(TVSR)　is　a　new　method　to　decrease　and　homogenize　the　residual　stress.　Based　on　the　stress　relaxation　tests　and　the　equivalent　vibration　equation　of　modal　analysis,　the　creep　constitutive　model　and　the　bilinear　isotropic　hardening　plasticity　material　model　(BISO)　are　combined　to　establish　the　numerical　simulation　model　of　TVSR　of　7075　aluminum　alloy　ring　part.　The　simulation　results　show　that　four　different　initial　blank　residual　stress　levels　are　obtained　after　quenching　process,　and　the　residual　stress　elimination　and　homogenization　effect　of　TSR　and　TVSR　is　better　than　that　of　VSR.　TVSR　has　a　better　effect　on　both　residual　stress　elimination　and　homogenization,　and　the　residual　stress　relief　rate　can　reach　more　than　20%.　©　2021　Trans　Tech　Publications　Ltd,　Switzerland.
