Research on Crankshaft Grinding Based on Gaussian Heat Source Model
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 ma-terial tissue phase change,and is verified by fluorescence flaw detection.
