摘　　要：以香蕉筛为研究对象,运用有限元分析软件ANSYS对其筛箱进行了谐响应分析。根据分析确定了香蕉筛应力集中和位移变形较大的位置,得出了筛体上几个关键点的位移-频率变化曲线。并对谐响应分析结果进行了说明,筛体后挡板横梁中间可能发生共振现象,同时也说明了谐响应分析的局限性。The harmonic response analysis of the sieving box of a banana screen was carried out by using ANSYS.According the analysis results,the location of stress concentration and large displacement were determined,and variation curves of displacement with frequency on several key points of the screen body were obtained also.In addition,the harmonic response analysis results was discussed,it was concluded that resonance probably occurred on the middle of beam of tailgate in the screen body.At the same time,the limitation of harmonic response analysis was explained.
