泡沫铝铣削力离散元仿真分析及实验研究
Discrete element simulation and experimental study on milling force of foam aluminum
摘要
Abstract
In order to study the milling force characteristics of porous metal aluminum foam,the main macroscopic mechanical properties of aluminum foam were measured by experiments.The discrete element simulation analysis model of aluminum foam was established by EDEM software,and its microscopic performance parameters were adjusted.The main macroscopic mechanical properties of aluminum foam obtained by simulation analysis were matched with the experimental results,and the final simulation analysis model was determined.Based on the orthogonal experiment principle and the discrete element simulation analysis method,the change rule of aluminum foam milling force with cutting amount was studied,and the empirical formula of cutting force index was established.The variation of milling force of aluminum foam with feed rate and cutting weight was studied by experimental method.The milling force results predicted by experimental research,simulation analysis and empirical formula are compared and analyzed.The results show that the cutting force obtained by the three methods is consistent with the change of milling amount,and the relative error is less than 10%.It is proved that the feasibility of using the discrete element simulation analysis method to study the milling force of aluminum foam and the accuracy of the established empirical formula of milling force.关键词
