摘　　要：为了研究强化研磨靶射距离对GCr15轴承钢塑性变形的影响,文章对不同靶射距离(60 mm、90 mm、120 mm和150 mm)的加工进行了仿真分析。仿真过程中靶射距离为单一变量,使用的仿真软件为离散元软件EDEM。仿真结果表明:随着靶射距离的增大,轴承钢在X轴和Z轴方向上的塑性变形量均先逐渐增大,后逐渐变小,呈现出近似抛物线的变化规律,其中靶射距离为90 mm的钢板变形量最大,靶射距离为60 mm的钢板变形量最小。轴承钢变形量的增加有助于形成表层更厚的强化层厚度,因此可以推断出靶射距离为60~120 mm时的轴承钢加工效果最好。In order to study the effect of the intensified grinding target shooting distance on the plastic deformation of GCr15 bearing steel,simulation analysis was conducted for different target shooting distances(60 mm,90 mm,120 mm,and 150 mm).The target shooting distance was a single variable in the simulation process,and the simulation software used was the discrete element software EDEM.The results show that with the increase of the target distance,the plastic deformation of the bearing steel in the X-axis and Z-axis directions first gradually increases and then gradually decreases,showing an approximate parabolic variation pattern.The steel plate with a target distance of 90 mm has the largest deformation,while the steel plate with a target distance of 60 mm has the smallest deformation.According to the increase in deformation of bearing steel,it helps to form a thicker strengthening layer on the surface,and it can be inferred that the best machining effect of bearing steel is achieved when the target shooting distance is 60~120 mm.
