振动偏心轮结构设计及其有限元分析

Structure Design of Vibration Eccentric and Its Finite Element Analysis

结合振动压实理论,为实现土壤的良好压实,设计了可提供合适的激振力、振动频率和名义振幅的偏心轮。基于有限元分析理论,提出了一种偏心轮强度的校核方法;对振动偏心轮进行模态分析,得到了其多个低阶固有振动频率和模态振型。所得结论为振动偏心轮物理参数和材料的选择等提供参考。

Combined with vibratory compacting theory,in order to compact the soil well,vibration eccentric was designed to provide the appropriate vibration force,vibration frequency and the name of amplitude.Based on the finite element analysis theory,this paper puts forward a kind of eccentric block intensity method.Its modal shape is analyzed and many of its low natural frequency and mode shapes are collected.The results provide the theoretical guide for vibration eccentric wheel physical parameters and the choice of materials.
