大型振动筛有限元模态分析

Analysis of the pattern of finite element for the large vibration screen

运用有限元软件ANSYS建立了大型振动筛整筛有限元模型,并对整筛动态特性进行分析,确定大型振动筛结构振动特性,对结构的刚度和质量分布进行调整,避免结构在外部作用激励下发生共振。

Setup with the software of finite element ANSYS finite element model of large vibration screen,structural vibration characteristic determined, structural stiffness and mass distribution adjusted, occurrence of resonance by external activation avoided.
