摘要
本文主要开展了单颗金刚石磨粒磨削碳化硅颗粒增强铝基(SiC_(p)/Al)复合材料的试验及三维有限元仿真研究。分析了SiC_(p)/Al复合材料磨削过程中磨削工艺参数对磨削力及表面形貌等的影响。分析结果表明,随着磨粒转速的增加,磨削力减小,SiC颗粒破碎现象有所缓解,铝基体的涂覆作用增强,表面形貌完整性好;随着磨削深度的增加,磨削力增大,SiC颗粒破碎明显增强,表面形成较多凹坑与孔洞,表面质量差。仿真结果与试验结果较吻合,说明该仿真模型可用于磨削工艺参数的优化分析。
The experiment and three-dimensional finite element simulation of single diamond abrasive grinding SiC_(p)/Al composites are carried out.The effects of grinding parameters on grinding force and surface morphology of SiC_(p)/Al composites were analyzed.The analysis results show that the grinding force decreases with the grinding speed increasing,the breakage of SiC particles is alleviated,the coating effect of aluminum matrix is enhanced,and the surface morphology integrity is good.The grinding force increases with the grinding depth increasing,SiC particle breakage is significantly enhanced,more pits and holes are formed on the surface,and the surface quality is poor.The simulation results are consistent with the experimental results,which shows that the model can be used to optimize the grinding process parameters.
