本科毕业设计论文题目：基于ansys的齿轮应力有限元分析学生姓名：所在院系：机电学院所学专业：机电技术教育导师姓名：完成时间：摘要本文主要分析了在ansys中齿轮参数化建模的过程。通过修改参数文件中的齿轮相关参数，利用APDL语言在ANSYＳ软件中自动建立齿轮的渐开线。再利用图形界面操作模式，通过一系列的镜像、旋转等命令，生成两个相互啮合的大小齿轮。运用有限元分析软件ANSYS对齿轮齿根应力和齿轮接触应力进行分析计算,得出两个大小齿轮的接触应力分布云图。通过与理论分析结果的比较,验证了ANSYS在齿轮计算中的有效性和准确性。关键词:ANSYS,APDL，有限元分析,渐开线，接触应力。ModelingandFiniteElementAnalysisofInvoluteSpurGearBasedonANSYSAbstractWehavemainlyanalyzedspurgearparametrizationmodellingprocessintheansyssoftware.usingtheAPDLlanguagethroughrevisesthegearrelatedparameterintheparameterdocument,weestablishesgear'sinvoluteautomaticallyintheANSYSsoftware.Then,usingthegraphicalinterfaceoperatorschema,throughaseriesoforders,mirrorimages,revolvingandsoon,weproducethebigandsmallgearwhichtwomeshmutually.Carringonthestressanalysisofthegearbyusingthefiniteelementanalysissoftware--ANSYS,weobtaintwobigandsmallgear'scontactstressdistributioncloudcharts.throughwiththetheoreticalanalysisresult'scomparison,weexplainANSYSinthegearcomputationvalidityandtheaccuracy.Keywords:ANSYS;APDL;finiteelementanalysis;involuteline;contactstress目录1绪论..............................................................52齿轮仿真分析方法..................................................63齿轮实体模型的建立方法............................................63.1直齿轮建模要求描述...........................................73.2渐开线的生成原理.............................................73.3创建渐开线曲线...............................................73.4齿根过渡曲线生成原理.........................................93.5创建齿廓特征................................................104齿轮接触应力分析.................................................134.1模型网格划分................................................134.2创建接触对..................................................144.3施加边界条件和载荷..........................................154.4求解........................................................164.5计算结果分析................................................174.5．1仿真计算分析.........................................174.5.2理论分析..............................................175齿根弯曲应力分析.................................................175.1建立齿轮模型................................................175.2划分网格....................................................185.3施加载荷和约束..............................................185.4求解........................................................185.5仿真分析与理论结果对比......................................196结论.............................................................19参考文献...........................................................20附录...............................................................21[1]大齿轮渐开线生成的命令流....................................21[2]大小齿轮的基本参数表........................................22谢辞...............................................................231绪论齿轮是机械中广泛应用的传动零件之一，形式很多，应用广泛。齿轮传动具有传动功率范围大、传动效率高、结构紧凑、传动比准确、使用寿命长、工作可靠性好等优点。因此齿轮传动技术成为机...
