| 摘 要： | 在磨削温度实验的基础上, 运用有限元法对工程陶瓷氧化铝及部分稳定氧化锆进行了高效深磨磨削温度场的仿真研究.基于磨削温度的实验和传热学理论,得出了工程陶瓷工件的磨削热分配比;得出了干磨及湿磨两种状态下工程陶瓷磨削温度场的分布; 并分析了磨削温度梯度对工程陶瓷热裂纹的影响.结果表明: 随着砂轮线速度增加, 磨削温度场温度梯度增大; 而随着磨削深度增大,不同材料的磨削温度梯度变化不同,且磨削温度梯度与磨削热裂纹的产生有一定的对应关系.

| Abstract: | Based on grinding temperature experiments, the grinding temperature fields in high-efficiency grinding of the two engineering ceramics, Al2O3 and PSZ ZrO2, are simulated by using finite element method. Based on grinding temperature experiment and heat transfer theory, grinding heat partition in engineering ceramics is obtained. Both the dry and wet grinding temperature distributions in the workpieces are obtained. The analysis indicates that the grinding temperature gradients in the temperature fields incre... |
