为了研究球磨机简体的动力学,必须知道当球体打击筒体时作用在筒体上的力谱。根据赫兹理论,两物体互相碰撞时,冲击力谱可由下式表示[1]: F(ω)=1.07mv_0|(cos(ωτ/2))/(1-(ωτ/2)~2)|(1)式中: m——互相碰撞物体的折算质量; v_0——互相碰撞物体在碰撞初始的相对速度; τ——碰撞时间。 In order to study the simplified dynamics of a ball mill, it is necessary to know the force spectrum acting on the cylinder when the latter collides with the cylinder. According to the Hertz theory, when two objects collide with each other, the impact force spectrum can be expressed by the following formula: F (ω) = 1.07mv_0 | (cos (ωτ / 2)) / (1- (ωτ / 2) (1) Where: m-- reciprocal collision mass of each object; v_0-- collision with each other at the initial collision relative velocity; τ-- collision time.
