圆盘剪分切的圆盘刀磨损机制仿真研究
|
摘要
基于对圆盘剪分切的圆盘刀磨损仿真建模,对不同侧向间隙、径向间隙和刃口锋利度的圆盘刀刃口磨损进行了仿真分析,对比分析了各工艺参数对刃口磨损深度和分布的影响。对圆盘刀分切能耗的分析表明板材分切能耗与刃口磨损的变化规律一致,可以通过分切能耗的大小表征磨损的程度。研究发现增大侧向间隙能显著降低磨损和能耗;改变径向间隙对磨损和能耗基本无影响;刃口锋利度下降,磨损和能耗整体上有所增大,但圆盘刀侧边的磨损减小。最后,基于Archard磨损理论,对不同加工参数下圆盘刀刃口的接触压应力和相对滑移速度的变化历史对比分析,建立了圆盘刀磨损模型。
Based on the wear simulation model of disc cutter in slitting process,the edge wear of disc cutter with different side clearances,radial clearances and edge sharpness was calculated and analyzed.The effects of various process parameters on the depth and distribution of the edge wear were compared.The analysis of slitting energy consumption shows that the law of slitting energy consumption and edge wear is consistent which means that the level of wear can be characterized by the amount of slitting energy consumption.It is found that increasing the side clearance can significantly reduce wear and energy consumption,while changing the radial clearance has little effect;when edge sharpness decreases,wear and energy consumption increase as a whole,but the wear of disc cutter side is reduced.At last,based on the Archard wear theory,the change history of contact compressive stress and relative sliding velocity of the disc cutter edge under different processing parameters were contrasted and analyzed,and the wear model of the disc cutter was established.
