提供全套毕业论文，各专业都有摘 要本课题的讨论内容是“小排量轿车车轮结构的有限元模态分析”。其主要内容是: (1)车轮的设计与建模；(2)车轮的有限元分析。首先介绍车轮的基本知识和设计技术要求，根据技术要求，同时参考其它相似小排量轿车车轮，设计出四款新车轮，然后通过 CATIA 软件完成实体模型的几何建模工作。借助 CATIA 的仿真分析模块对所设计的四款车轮进行有限元分析，包括静强度分析和模态分析，仿真计算出各个车轮的等效应力分布、固有频率和振型，对结果进行分析比较。分析结果表明：经有限元分析得到的结论基本与实际情况相符合，且设计方案一和设计方案二的轮辐结构较为合理，轮辐结构的受力均匀且远小于所用材料的许用应力，符合设计的要求。本论文的讨论工作可以为铝合金车轮的研制和开发提供一定的参考。关键词: 铝合金车轮，强度分析，有限元分析，模态分析，CATIASmall Displacement Passenger Vehicle Wheel Structural Modal Finite Element AnalysisABSTRACTThe subject is to discuss “Small displacement passenger vehicle wheel structural modal finite element analysis”. The major content is (1) design and modeling (2) finite element of the wheel.First, introduce the basic knowledge and technology requirement of the wheel, according to the technology requirement. At the same time refer to other small displacement vehicle wheel, then design four new wheel, through CATIA software to accomplish the modeling.Use CATIA to analysis the model and analysis the four wheel, include strength analysis 、 modal analysis, to calculator every wheel’s stress distribution、natural frequency、vibration patterns, compare with the result, with the fitness of the basic performance, choose the structure to design a more reasonable wheel design project. The analysis result indicated that, The conclusion obtains which after the finite element analysis basically tallies with the actual situation, also design proposal one and design proposal four spokes structures more reasonab...
