以结构力学理论为依据，以有限元ＳＡＰ５程序为计算手段，提出了一种直线振动筛侧板的动力学强度的计算方法，并分析了这类振动筛在侧板上产生裂纹的原因．
Based on the theory of structural mechanics and using finite element program SAP5 as a calculation method, a calculation method of the dynamic strength of the side plate of a linear vibrating screen is proposed, and the reason of the crack on the side plate of the vibrating screen is analyzed.
