基于双层胶合模型的蜂窝纸板分切仿真
Honeycomb Board Based on Double-Layer Gluing Model Slitting Simulation
摘要
Abstract
To explore the influence of different cutting paths on cutting force and slitting quality,the simulation study on the straight knife slitting process of honeycomb board as the research object was carried out.Firstly,the influence of the gluelayer on the slitting profile and cutting force was analysed;secondly,a structural simulation model of honeycomb board was established using the double-layer gluing modelling method to investigate the causes of the slitting profile under different slitting paths,and the cutting forces in X and Y directions were compared;finally,the maximum stresses in the slitting process of each path were extracted,and a more ideal slitting path was obtained.The results of the analysis show that the gluelayer can improve the slitting quality of honeycomb board,and reduce the change in cutting force;different slitting paths show different slitting profiles,among which the slitting path 3 has less cutting force in the X and Y directions,less defects in the slitting profile of honeycomb board and honeycomb core wall fracture,and the stress change in the slitting process is smaller,which is a more ideal slitting path.关键词
