增强颗粒团聚分布SiCp/Al复合材料切削模拟研究
Study on Cutting Simulation of SiCp/Al Composites With Reinforced Article Agglomeration Distribution
摘要
Abstract
In order to study the effect of reinforced particle agglomeration distribution on the cutting process of SiCp/Al composites,three orthogonal cutting finite element models with different SiC particle agglomeration size ratios were established and verified.The results show that with the increase of particle agglomeration size ratio,the continuity of sawtooth chip decreases and the shape becomes more irregular,and correspondingly the fluctuation degree,average value and peak value of cutting force increase.The cutting stress in the agglomeration area increases with the agglomeration size ratio increasing.Larger particle agglomeration size ratio leads to an increase in subsurface damage depth and maximum contour peak and valley height.关键词
