摘要:
利用直剪仪测定了在不同法向压应力（25,50,75,100 kPa)条件下大豆（含水率分别为10.62%、12.32%、13.84%、15.23%、17.02%)与不同仓壁材料（不锈钢板、混凝土板、木板)的摩擦系数。结果表明：大豆与不锈钢板的摩擦系数最小，与木板的摩擦系数较大,与混凝土板的摩擦系数最大，摩擦系数范围分别是0.317~0.420，0.323~0.453，0.357~0.533；在含水率一定的条件下大豆与仓壁材料的摩擦系数随着法向压应力的增大而减小，法向压应力一定的条件下大豆与仓壁材料的摩擦系数随着含水率的增大而增大。最后，分别拟合了摩擦系数与法向压应力和大豆含水率的一元二次关系方程。
Abstract:
In this article,the coefficient of friction between soybeans and silo wall materials were measured by direct shear apparatus.The results showed that as the moisture contents increased from 10.62% to 17.02%,the coefficient of friction between soybean and materials which were stainless steel,concrete and board ranged from 0.317 to 0.420,0.357 to 0.533 and 0.323 to 0.453，respectively.The coefficient of friction between soybean and stainless steel was the smallest，the coefficient of friction between soybean and concrete was the biggest.Coefficients of friction decreased with the increasing of normal stress and increasing with the increase of moisture content.Finally,the relationship between the coefficient of friction and moisture content,the coefficient of friction and the normal stress were fitted as functions,respectively.
