| 摘 要： | 根据实际工况建立接触网腕臂结构系统的有限元模型。利用有限元法对此模型进行受力分析,校核其静强度、静刚度。建立腕臂结构系统的动力学模型,通过模态分析得出模型的前10阶固有频率及振型,并通过谐响应分析计算在外载荷的影响下结构的共振频率。通过对腕臂结构系统的动力学分析,得出在外载荷作用下,整体结构系统不会发生共振现象,与实际工程项目相符,为工程实际提供理论支持。

| Abstract: | A finite element model of cantilever structure is created based on engineering practices. Static analysis is conducted with finite element method to test the model's strength and stiffness. Then a dynamic model is established and modal analysis is conducted to get the first ten natural frequencies and corresponding modes. Resonance frequency is obtained through harmonic response analysis under the influence of external load. Finally,conclusions are made that the overall structure is not subject to resonance vibration and complies with engineering actuality, which provides theoretical support to engineering practice. |
