毕业设计说明书I2110柴油机(曲轴飞轮)设计摘要2110柴油机是在2100柴油机的基础上自行改进与开发研制的新型、中等功率、节能的柴油机。目前，该机型已经广泛运用于我国的农用工程机械，小型发电等领域。2110柴油机与同类机型相比，具有先进的动力性，经济性和可靠性，在国内农用机械用户中具有很强的优势。与2100系列柴油机相比，2110柴油机主要在发动机机体、气缸盖、活塞连杆总成、曲轴、燃油系统等方面进行了优化、强化设计，使发动机在动力性、经济性等方面有较大的提高，也实现了增加其运用范围的目的。本文主要介绍了2110柴油机的总体设计思想的确定以及曲轴飞轮组零件的设计过程。内容包括2110柴油机总体设计方案的选择，动力性指标的确定，曲轴飞轮零件图的绘制时的参数选择，包括曲轴结构的设计，制造时所需注意的加工过程以及检验产品时强度校核等内容。本文运用到了UG三维软件制图，用以解决曲轴的油道与曲柄销减重孔的干涉问题，同时用Ricardo计算方法解决曲轴疲劳强度问题。本文综合性的对曲轴飞轮组的设计问题进行了研究。关键词：柴油机，曲轴，飞轮，UG毕业设计说明书IITHEDESIGNOF2110DIESELENGINE(CRANKSHAFTandFLYWHEEL)ABSTRACTOnthebasisofthe385dieselengine,2110dieselengineimprovetoanewstyle,whichishigh-speed,medium-powerandenergy-savingdieselengine.Atpresent,themodelshavebeenwidelyusedinChina'sagriculturalengineeringmachinery,smallpowergeneration.Comparedwithsimilartypedieselengine，2110dieselenginehasadvancedperformance,economyandreliabilityinthedomesticagriculturalmachinery,andtheyhavemillionsofusers.Comparedwith2100seriesdieselengine,2110dieselenginesaremainlyimproveintheengineblockandcylinderhead,pistonconnectingrod,crankshaft,fuelsystem,andimprovetheoptimizationdesign,thatimprovetheenginepower,economy,italsoachievethepurposethatincreasingitsapplicationscope.Thispapermainlyintroducestheoveralldesignthoughtof395dieselengine,crankshaftandflywheelthedesignprocess.Thesisincludeshowtoselected2110dieselengine,theoverallperformanceindicatorsidentified,andtheprocessofthedesignofthecrankshaftflywheelwillbediscussedinthispaper.Includingthecrankshaftstructuredesign,whatwemustpayattentiontoinmanufactureprocess.ThispaperusesUG3Dsoftwaretodrawcrankshaft,itsolvetheoilholewiththeweightreducingholeofinterferenceproblems.AndwithRicardocalculationmethod,itsolvethecrankshaftfatiguestrengthproblems.Thispapercompletelydiscussthedesignofcrankshaftandflywheel.KEYWORDS：Dieselengine，crankshaft，flywheel，Ricardocalculationmethod，UG毕业设计说明书III目录第一章前言...................................
