摘要

为了研究复合喷丸的工艺效果，利用ABAQUS 有限元仿真软件进行模拟分析，建立了34CrNiMo6 钢随机多弹丸的周期性三维有限元模型。首先对所提出的周期性有限元模型进行周期性验证和试验验证，然后利用周期性有限元模型对复合喷丸的强化效果、不同喷丸强度对残余应力场的影响进行分析。结果表明：该周期性三维有限元模型可有效模拟喷丸强化效果；复合喷丸强化使34CrNiMo6 钢表面产生的残余应力和最大残余应力均高于单一喷丸产生的，且表面残余应力分布更加均匀，但最大残余应力所处深度不变；复合喷丸可得到更小的表面粗糙度。

Abstract

To study the effect of dual peening

the periodic 3D finite element model of 34CrNiMo6 shot peening with a number of random projectiles is established using finite element analysis software ABAQUS. At first

the proposed periodic model is verified by experiment. Then the strengthening effect of shot peening and the influence of Almen intensity on residual stress field are analyzed with the proposed periodic model. The results show that the residual stress on surface layer of 34CrNiMo6 caused by dual shot peening is larger than that caused by single shot peening

and the residual stress distribution on surface is more uniform

but the depth of maximum residual stress is the same. Dual shot peening can attain less surface roughness.
