铝蜂窝夹层结构钻削加工仿真与试验研究
Simulation and Experimental of Drilling Aluminum Honeycomb Sandwich Structure
摘要
Abstract
In order to improve the machining quality of the drilling process of aluminum honeycomb sandwich structure,the drilling experiment and finite element simulation analysis were conducted.Firstly,through the combination of experiment and simulation,the deformation characteristics of honeycomb wall after drilling and the influence of process parameters on the deformation were investigated;on the basis of confirming the accuracy of the simulation model,the change characteristics of axial force and torque of honeycomb sandwich structure in drilling were analyzed by combining with the feeding process of the drill.The results show that the honeycomb wall deformation increases significantly with the growth of feed rate,and both axial force and torque show obvious stage changes during drilling.It can provide a reference for the reasonable selection of drilling process parameters of aluminum honeycomb sandwich structure.关键词
