摘要
通过可加工陶瓷多磨粒磨削有限元仿真,研究了磨粒数目等因素对应力应变的影响。结果表明:2磨粒磨削应力和应变变化趋势相似,随磨削速度增大,2磨粒磨削应变小于3磨粒应变;3磨粒磨削时,磨粒深度达到1.2mm后应力和应变开始显著增大。
By finite element simulation of multiparticles grinding, the stress and strain were studied in machining ceramics of grinding process. The simulation results indicated： the variation trend of stress and strain is similar in grinding of the 2 abrasive grains. With increasing of the grinding speed, the strain of the 2 abrasive grains is less than that of the 3. When the grinding depth is greater than 1.2mm, the stress and strain is significant increase.
