本文应用试验模态分析方法研究了振动着的物料的载荷效应,发现了这种载荷是一系列冲击力的作用,导出了动载荷的表达式,发现了高次谐波共振现象,这些结果可用于振动筛框的动强度设计中。
In this paper, the modal analysis method is used to study the loading effect of the vibrating material. It is found that the load is a series of impact force. The expression of dynamic load is derived and the phenomenon of higher harmonic resonance is found. These results are available Vibration screen box in the dynamic strength design.
