[目的]探究气鼓轮砂带砂光参数对磨削力的影响以及磨削力与砂光表面粗糙度的关系,为更好控制气鼓轮砂带砂光木(板)材的表面粗糙度提供理论参考.[方法]开展气鼓轮砂带砂光饰面中密度纤维板的单因素试验,运用流体腔理论建立气鼓轮砂带砂光饰面中密度纤维板的有限元模型,基于有限元模型和单因素试验,探究气鼓轮气压、进给量、轴平行度误差对磨削力和砂光表面粗糙度的影响,并分析磨削力与砂光表面粗糙度的关系.[结果]随着气鼓轮气压、进给量、轴平行度误差增加,试件总磨削力增大,但其引起总磨削力增大的原因不同;试件接触中心节点法向应力大小主要与气鼓轮气压有关;对应同一试件的中间区域(6～59 mm...

[Objective]In order to provide theoretical reference for better controlling the sanding surface roughness of the wood board with air-drum belt sanding,the effect of sanding parameters on grinding force and the relationship between grinding force and sanding surface roughness were studied.[Method]The main research contents included:we carried out the single factor tests on the air-drum belt sanding MDF(medium-density fiberboard),established the finite element model of the air-drum belt sanding MDF,based on fluid cavity theory.By combining the finite element model with the single factor tests,we...
