三辊卷板机关键零部件有限元分析.doc

XX大学 毕 业 设 计（论 文） 设计（论文）题目：三辊卷板机关键零部件有限元分析 摘 要 有限元分析是用较简单的问题代替复杂问题后再求解。它将求解域看成是由许多称为有限元的小的互连子域组成，对每一单元假定一个合适的(较简单的）近似 解，然后推导求解这个域总的满足条件(如结构的平衡条件），从而得到问题的解。这个解不是准确解，而是近似解，因为实际问题被较简单的问题所代替。由于大 多数实际问题难以得到准确解，而有限元不仅计算精度高，而且能适应各种复杂形状，因而成为行之有效的工程分析手段。 由于某些原因，没有上传完整的毕业设计（完整的应包括毕业设计说明书、相关图纸CAD/PROE、中英文文献及翻译等），此文档也稍微删除了一部分内容（目录及某些关键内容）如需要的朋友，请联系我的叩扣:2215891151，数万篇现成设计及另有的高端团队绝对可满足您的需要. 本设计是基于ANSYS软件来对三辊卷板机关键零部件进行分析。与传统的计算相比，借助于计算机有限元分析方法能更加快捷和精确的得到结果。设置正确的模型、划分合适的网格，并合理设置求解过程，能够准确的获得分析模型各个部位的应力、变形等结果。对零件的设计和优化有很大的参考作用。 关键词：卷板机；三维建模；ANSYS；动静态分析 Abstract Finite element analysis is to use simpler problem instead of solving complex problems after. It will solve the field as much as by finite element of small interconnect subfields, each unit is assumed to be a proper ( simple ) approximate solution is derived, then solve the domain satisfying conditions ( such as structural equilibrium conditions ), resulting in the solution of problems. This solution is not accurate solution, but the approximate solution, because the actual problem is simpler problem place. Because most practical problems difficult to obtain accurate solution, and the finite element computation of not only high precision, but also can adapt to a variety of complex shapes, thus become effective engineering analysis method. The design is based on the ANSYS software on the three roller bending machine key components analysis. Compared with the traditional calculations are compared, with the help of computer finite element analysis method can be more efficient and precise results. Set the correct model, dividing the appropriate grid, and set a reasonable solution process, can accurately obtain analysis model of various parts of the stress, deformation and other results. The design and optimization of parts have great reference value. Key Words: bending machine;3D modeling; ANSYS; static analysis 目 录 TOC \o 1-3 \h \z \u 摘 要 II Abstra
