香蕉型振动筛静力学与固有特性有限元分析

Finite Element Analysis of Statics and Natural Properties of Banana-type Vibrating Screen

采用参数化建模方法建立振动筛的有限元模型,对其进行模态分析和静力学分析,计算出筛箱结构的固有频率、固有振型、应力分布,为振动筛动力学计算和优化设计提供依据.

In this paper , the finite element model of a vibrating screen is created by parame- trization modeling. Through its modal analysis and static analysis, the natural frequency, natural vibration mode and stress distribution of the structure are worked out, so they could provide the basis for the dynamics and the design optimization of the vibrating screen.
