It can be used to transfer space between any two axis movement and force, has large transmission power, high efficiency and transmission ratio accurate, long service life, work safety and reliability, etc. As mechanical science and manufacturing technology rapid development, the accuracy of the mechanical transmission systems have higher demands, gear finite element analysis research by foreign and domestic scholar attention.This article by using software of Workbench papers on fing spur gears finite element analysis, including plane static analysis, gear contact analysis. First of all, using AutoCAD software is built spur gear entity model and the gearing mesh entity model。 Secondly, in the Workbench, using the software with AutoCAD and of the interface between the entity model of the import, respectively。 Again, in the Workbench software in each of the two models, get their finite element analysis of the stress distribution and deformation figure。 Finally, to spur gear meshing gears and vice respectively with theoretical calculation of static contact, and the result of finite element analysis and paring the results.Keywords: Cylindrical spur gear。 Finite element analysis。 Contact problem目 錄摘要 ..................................................................................................................................................IAbstract ...........................................................................................................................................II1 緒論 ..............................................................................................................................................1 論文研究的目的和意義 ..........................................................................................................1 齒輪常見的失效方式和改進措施 ..........................................................................................1 失效分析 ..............................................................................................................................2 改進措施 ..............................................................................................................................3 本論文研究的主要內(nèi)容和特點 ..............................................................................................42 有限元法介紹 .............................................................................................................................5 有限單元法的發(fā)展及應用 ......................................................................................................5 有限單元法的基本原理 ..........................................................................................................6 Workbench 軟件特點 ..............................................................................................................7 Workbench 的靜力分析功能 ..............................................................................................7 Workbench 的接觸算法及分析功能 ..................................................................................8 本章小結(jié) ..................................................................................................................................93 直齒圓柱齒輪的建模 ...............................................................................................................10 齒輪建模軟件的選擇 ............................................................................................................10 AutoCAD 2022 軟件簡介 ......................................................................................................10 直齒圓柱齒輪的建模過程 ....................................................................................................11 直齒圓柱齒輪的基本參數(shù) ................................................................................................11 直齒圓柱齒輪建模的主要過程 ........................................................................................11 本章小結(jié) ................................................................................................................................134 直齒圓柱齒輪的有限元分析 ...................................................................................................14 直齒圓柱齒輪有限元模型的建立 ........................................................................................14 直齒圓柱齒輪靜力分析 ........................................................................................................14 添加材料的屬性 ................................................................................................................14 Workbench 分析 ................................................................................................................15 直齒圓柱齒輪接觸有限元分析 .....................
