【摘要】 本研究采用多元线性回归分析法,在磨削淬硬实验的基础上建立了40CrNi MoA钢的切向磨削力试验公式,并结合Rowe和Pettit的热量分配系数公式,运用有限元法对不同磨削用量下的淬硬层厚度进行了预测,得到了磨削深度、工件进给速度和磨削速度对淬硬层厚度的影响规律,从而为制订、实施和优化磨削淬硬工艺提供了基础。更多还原

【Abstract】 According to the grind-hardening test and using the multiple linear regression analysis,the experimental formula of the tangential grinding force is established in this paper.Combined with the heat distribution coefficient formula of Rowe and Pettit,the thickness of the grind-hardening layer is predicted by using the finite element method under different grinding parameters.It draws the influence law of the grinding speed,cutting depth and feeding rate to the thickness of the grind-hardening layer.It provided the basis to the drawing up,the application and the optimization of the grind-hardening process.更多还原
