摘　　要：将坚果与碾盘的相互作用简化为带有固定端约束的圆环（半径为Ｒ），采用力法建立了可能危险截面上的弯矩与磨盘间距的关系．数值计算表明优化磨盘间距为３．３１７Ｒ．The interaction of nuts and millstone was modeling as circles (with radius R) with fixed- end constraint. The force method was adopted to construct the relationship between bending moment at possible peril point and millstone gap. The cal- culation tesults show that the optimum gap D is 3.317R.
