摘要
通过利用三维建模软件Solidworks对齿轮进行精确建模,然后将实体模型导入ANSYS有限元分析软件,并通过选择单元类型、定义材料模型、划分网格等一系列操作建立机构的有限元模型。介绍了基于ANSYS的模态分析理论,通过加载条件,求解出固有频率,通过扩展模态,从而获得齿轮机构的5阶模态参数。通过这样的分析研究,能够大大减少发生共振的可能,并且对于齿轮的优化设计和故障诊断提供了参考依据。
By using three-dimensional modeling software Solidworks accurately modeled gear, and then the solid model into ANSYS finite element analysis software, and by selecting the unit type, the definition of material model, a series of operations meshing finite element model agencies. Introduced based on modal analysis theory ansys by loading conditions, the natural frequency solved by expanding modal, so as to obtain 5 modal parameters of gear mechanism.Through this analysis, it can greatly reduce the possibility of resonance, and for optimizing the design and troubleshooting gears provide a reference.
