摘　　要：磨削加工产生的温度场会根据自身分布特性对试件造成不同程度烧伤。提出改进的平面磨削热量分配理论模型并结合ABAQUS建立磨削温度场有限元模型,基于热成像法提出一种研究试件表面温度场分布的方法,并对仿真结果进行了验证,利用表面形貌对加工质量进行了分析。结果表明:仿真结果和实际加工过程的温度相对应,且靠近工件中心1 cm范围内都是高温区域;磨削高温所影响的深度大约只存在于温度影响深度的前1/3。The temperature field produced by grinding would cause different degrees of burn to the specimen according to its own distribution characteristics.An improved theoretical model of heat distribution in surface grinding was proposed, and the finite element model of grinding temperature field was established with ABAQUS.Based on thermal imaging method, a method to study the surface temperature field distribution was proposed, the simulation results were verified, and the processing quality was analyzed by surface morphology.The results show that the simulation results correspond to the temperature of the actual machining process, and the high temperature area is within 1 cm near the center of the workpiece;the depth affected by grinding high temperature only exists in the one third of the depth affected by temperature.
