在关于缓磨时的磨削热 ,接触弧区换热过程以及工件表层非稳态温度场的深入研究的基础上 ,构造了一可用于计算缓磨烧伤前后工件表层温度场畸变历程的数学模型 ,并据此完成了关于缓磨烧伤过程的计算机仿真研究 ,仿真结果与实际吻合良好 ,它率先阐明了缓磨烧伤的热机理并且证明了缓磨烧伤是一具有明显前兆特征的典型渐变过程 Based on the deep research on grinding heat during buffing, heat transfer in contact arc zone and unsteady temperature field of workpiece surface, a mathematical model that can be used to calculate the surface temperature field distortion before and after burnishing is constructed , And then completed the computer simulation study on the process of buffing burn. The simulation result is in good agreement with the actual situation. It took the lead in clarifying the thermal mechanism of buff-burns and proved that buff-burring is a typical gradual process with obvious precursor features
