基于Matlab的三轴惯性振动筛力心解析

在振动筛设计中,力心与质心的位置关系直接决定着振动筛的运动轨迹,因此力心的存在性及其位置确定非常重要。给出了三轴惯性振动筛力心的定义,建立了三轴惯性振动筛的简化模型,借助Matlab软件采用解析方法证明出其力心的唯一存在性,并进行了3个实例的力心位置计算。结果表明:三轴惯性振动筛有力心存在,且是唯一确定的。

Analysis of Forcecenter for ThreeAxis Inertial Shale Shaker Based on Matlab

In the process of designing shale shaker, the ubiety between forcecenter and masscenter directly determined the shaker＇s movement locus, therefore, it＇s significance to prove the existence of forcecenter and where its location. First of all, concept of the forcecenter for ThreeAxis Inertial Shale Shaker was put forward. Then, its simplified model was built up. Moreover, it proved the uniqueness and existence of this forcecenter by using the powerful computing tool Matlab. Finally,the center＇s location within three examples was figured out by evaluating each parameter. Theory and examples both showed that the ThreeAxis Inertial Shale Shaker＇s force center existed, and it was unique.
