基于ANSYS-Workbench的模块化绞车有限元模态分析

摘要

Based on the real size of marine seismic modular winch,the three-dimensional modal in Solidworks was con-structed,then the modal was imported to the finite element software ANSYS Workbench.After defining material and mesh,researchers carried out modal analysis of the modular winch.The results showed:the former six natural frequency was focused on 10~40,Hz,and the maximal deformation appeared in the top cross beam and the rim of wheel hub.The paper provides a reliable theoretical basis for the design and has a directional guidance significance to the optimization ofthe structure of the modular winch.%针对海洋地震拖缆模块化绞车，基于Solidworks完成绞车框架及卷筒三维实体模型的建立，并将模型导入有限元分析软件 ANSYY-Workbench，在完成对绞车材料的定义并划分网格后对其进行模态分析。通过计算得出模块化绞车的前六阶固有频率集中在10～40,Hz，绞车滚筒与其液压马达的工作不会与其产生共振，通过对其振型的分析得出振动形变较大区域为框架顶端横梁部分及绞车轮毂边缘，计算结果为绞车的设计提供了可靠的理论依据，且对结构的优化提出了方向性建议。
