grain pre cleaner

The quality of grain cleaning depends on four design parameters : oscillating frequency, acceleration and the direction, and velocity of air flow under fixed working conditions.

在现有气流振动筛选谷物清选机构使用条件一定的情况下,选择影响清选工作质量的4个主要运动学参数,即振动频率、加速度大小和加速度方向角以及气流速度作为设计变量,通过回归正交设计和台架试验的方法建立了清选工作质量与4个设计变量之间的数学模型,并通过优化设计求出这4个设计变量的最优配合方案。
