摘　　要：为了更好地分析磨削过程中温度场的分布情况,获得磨粒有序化排布砂轮磨削工件表面温度的变化规律,对磨粒有序化排布的砂轮进行了三维建模,并利用有限元仿真软件Abaqus,对磨粒叶序排布、错位排布、矩阵排布和无序排布砂轮磨削温度场分别进行有限元仿真.分析了磨削液、磨削深度、砂轮线速度和工件进给速度对磨削工件表面最高温度的影响.结果表明,在相同磨削条件下,磨粒叶序排布砂轮磨削工件表面的最高温度相较于其他3种排布形式最低.In order to analyze the distribution of the grinding temperature field and achieve the variation of peak surface temperature, the model of the engineered grinding wheels were established. By using the finite element simula- tion software Abaqus, the grinding temperature fields of the engineered grinding wheel with abrasive of random, array, phyllotactic and staggered configuration were simulated. The grinding temperature filed caused by different grinding depth, grinding wheel speed and workpiece feed speed were analyzed. The simulated results showed that the highest grinding temperature of the grinding wheel with abrasive phyllotactic pattern was the lowest in the same conditions.
