摘　　要：为了探究喷丸角度对材料为18Cr2Ni4WA的螺旋锥齿轮齿面与齿根表面及深度方向上残余应力分布的影响。利用ABAQUS有限元软件分别构建了单齿齿面及齿根喷丸有限元模型,分析了齿面与齿根在3种喷丸角度下的仿真结果。结果表明:在多弹丸随机喷丸条件下,与平面靶材的最佳喷丸角度为90°不同,作用于齿面的最佳喷丸角度为60°,齿面产生的残余压应力峰值为941.68 MPa;与齿面模型基于同一坐标系进行齿根喷丸角度设置,作用在齿根的最佳喷丸角度同样也为60°,齿根在此条件下产生的残余压应力峰值达1018.74 MPa。同时在进行螺旋锥齿轮齿面喷丸强化相关仿真中,应同时考虑其在x轴与y轴方向上的残余应力分布情况。To investigate the effects of shot peening angles on the residual stress distribution on the tooth surface and tooth root surface and in the depth direction of spiral bevel gear with material of 18Cr2Ni4WA,ABAQUS finite element software was used to construct the single tooth surface and tooth root shot peening finite element models,and the simulation results of tooth surface and tooth root with three shot peening angles were analyzed.The results show that under the condition of multi-projectile random shot peening,the optimal shot peening angle is 60°,which is different from the plane target′s optimal shot peening angle of 90°,and the peak residual compressive stress on the tooth surface is 941.68 MPa.Based on the same coordinate system as the tooth surface model,the shot peening angle of the tooth root was set.The optimal shot peening angle acting on the tooth root is also 60°,and the peak residual compressive stress of the tooth root under this condition reaches 1018.74 MPa.At the same time,the residual stress distribution in x-axial and y-axial directions should be considered in the simulation of shot peening on the tooth surface of spiral bevel gear.
