摘　　要：以某振动输送落砂机为分析对象,通过SolidWorks软件建立三维实体模型,导入有限元分析软件ANSYS Workbench进行预应力模态分析,得到落砂机前12阶模态频率,进行简谐激振力下的谐响应分析,得到振动体落砂台面在Y轴方向的幅值-频率响应云图,为落砂机结构设计和优化提供参考。Taking a vibration conveying shakeout machine as the analysis object,a three-dimensional solid model has been established through SolidWorks software,while the finite element analysis software ANSYS Workbench has been imported to carry out prestress modal analysis and the first 12 modal frequencies of the shakeout machine have been obtained.The harmonic response analysis has been conducted under the vibration force to obtain the amplitude-frequency response cloud diagram of the shakeout table of the vibrating body in the Y-axis direction,which provides a reference for the structural design and optimization of the shakeout machine.
