摘　　要：曲轴的磨削过程中,磨削参数选择不当,易引起磨削区温度过高,导致轴颈表面烧伤。针对这一问题,参照已有研究,通过对比三种不同的热源模型,验证高斯热源模型的适应性,并应用该模型预测曲轴连杆颈表面的温度,通过瞬态热分析与材料组织相变探究磨削烧伤机理,并利用荧光探伤检测对其进行验证。During the grinding process of crankshafts,improper selection of grinding parameters is prone to cause excessive temperature in the grinding zone,resulting in burns on the journal surface.In order to address this problem,with reference to the existing research,the adaptability of Gaussian heat source model is verified by comparing three different heat source models and applying the model to predict the temperature of crankshaft connecting rod journal surface,and the grinding burn mechanism is probed by transient thermal analysis and material tissue phase change,and is verified by fluorescence flaw detection.
