1、 I 摘要 挖泥设备尤其是挖泥船如今在中国得到了快速的发展，在港湾建设，清理河 道等方面发挥着巨大的作用。其中，挖泥船工作转台中的传动滚筒发挥着重要的 作用。起到了支撑和帮助工作转台转动的功能。其性能直接影响到了挖泥船的工 作运行。本论文采用了ADAMS测量出传动滚筒所受应力后运用ANSYS有限元分析软 件对其进行分析，对工作转台在一个工作周期内分别应用静态分析和动态分析对 传动滚筒所受的全部载荷做了全面的分析研究，通过后处理得到了传动滚筒的应 力和位移云图。最终确定了传动滚筒所受应力的状况。解决了挖泥船工作转台中 滚筒的实际问题。具有良好的经济效益和工程意义。 首先，对传动滚筒的类型和失效形

2、式做出简单的分析，通过已知的传动滚筒 的结构尺寸参数建立传动滚筒模型， 然后在已建立的ADAMS船体模型的基础上添加 适当的约束并运用ADAMS自身功能测量和绘制传动滚筒的应力曲线图。其次，由于 在ANSYS中建立滚筒模型较麻烦， 所以通过Solidworks建立传动滚筒模型并将其导 入进ANSYS。 最后将ADAMS测量出的应力曲线图拟合成方程函数并通过ANSYS对传动 滚筒所受应力进行分析，分为瞬时动态分析和静态分析，通过后处理分别得到静 态时传动滚筒在最大应力情况下的位移形变图和应力云图以及在挖泥船一个工作 周期内滚筒体上某一节点所受应力随时间变化的图和在某一时刻时该节点的位移 形变趋势

The dredger plays a significant role in the construction of harbor and the clearance of river course. The driving drum in the turntable of a dredger is especially important in working

4、, for it supports the whole turntable as well as helps it to rotate. Therefore, the performance of driving drums directly determines the working operation of dredgers. This essay analyzes the driving drum in ANSYS finite element analysis after measuring its exerted stress with ADAMS, makes a complet

5、e research on all loads of it during a work cycle of the turntable in static analysis and dynamic analysis respectively, and figures out its stress and displacement contour according to Solve and Plot Result of ANSYS, which determines its stress status and benefits in resolving the practical issues

6、of driving drums in turntables. This research is helpful to improve the economic efficiency and engineering significance of constructing dredgers as well. First, making a simple analysis about types and failure forms of drums then build drums model by dimension parameters which were detected. And add appropriate constrains on the driving drums to detect and map the charts of stress and displacement. Secondly, using Solidworks builds drums model because it is little complex in ANSYS. Finally, f
