毕业论文：液压油泵虚拟装配及部件有限元分析

摘要YOTCHP8756液压油泵是大连液压机械厂的主要产品之一。它的工作效率和容积效率都比较高，可以广泛应用于很多场合。但该厂产品开发手段基本是传统的串行方法，设计试制出原型样机，然后测试、验证并分析它们，但是由于工程师设计出产品，往往要经过多次反复的试制才能成功进入市场，产品开发时间长；在对设计大型、复杂程度较高的产品时，由于设计手段及生理因素的限制，设计易出错和人为疏漏，并缺乏对产品的制造、装配工艺性的预见，影响设计质量；产品设计、制造费用高，产品成本上升，缺乏市场竞争力。通过使用虚拟装配技术能够更加真实生动的反应液压油泵的装配过程，为了能够了解在实际载荷下关键部位的变形和应力的情况还需要使用到有限元分析技术。本次毕业设计是在3dsmax软件环境下对液压油泵进行虚拟装配动画制作，通过三维动画生动的描述液压油泵的装配过程。同时在HyperMesh软件下环境下进行单元网格划分和有限元分析，通过分析的结果真实反映出液压油泵的轴受力及载荷的状况。关键词：液压油泵虚拟装配液压泵轴有限元分析AbstractTheYOTCHP8756hydraulicpressurepumpisthemainproductsoftheDalianhydraulicpressuremachinefactory.Itsworkefficiencyandthecapacityefficienciesareallhigh,andcanbeusedinlotsofsituations.Butthefactory'sproductsdevelopmentisbasiconatraditionalmethod.first,theydesignmanufacturesasaprototypemachineonatrialbasis,thenmakethetest、verifyandanalyze.Becauseengineersdesigntheproducesusuallybaseonmanytimesmanufacturetrial,onlyafterthemanufacturetrial,theproducescansucceedputintothemarket,itmeansthetimeofproductdevelopingistoolong;Becauseofthedesignrestrictandthephysiologyfactor,thenwhentheydesignthemorelargeandcomplicatedproduct,designwouldmakemistakesandartificialcarelesseasily,andlacktheforeseeoftheproductmanufactureandassemblecraft,thiscanbeainfluencetodesignquantity;Italsomakemoredesigning、manufacturingexpenseoftheproduct,theproduct'scostwouldberising,thentheproduceslackthecompetitionability.Throughtheuseofmorerealisticvirtualassemblyvividresponsetohydraulicpumpassemblyprocess,inordertounderstandthekeypartsintheactualloadofthedeformationandstressofthesituationalsoneedtousefiniteelementanalysistechniques.Thegraduationprojectistheenvironmentin3dsmaxsoftware,virtualassemblyofhydraulicpumpanimation,animatedbyavividdescriptionofthree-dimensionalhydraulicpumpassembly.WhileundertheHyperMeshsoftwareenvironmentforcellmeshandfiniteelementanalysis,reflectedthroughthetrueresultsofHydraulicpumpshaftbytheforceandloadconditions.Keywords:hydraulicpressurepumpvirtualassembleHydraulicpumpshaftFEA目录引言....................................................................................................................................3第一章绪论........................................................................................................................41.1液压油泵的基本原理.....................................................................................................41.2液压油泵的发展情况.....................................................................................................41.3YOTCHP8756液压油泵特点............................................................................................51.3.1液压油泵的优缺点.....................................................................................................51.3．2该厂产品内容简介...................................................................................................61.4设计研究的内容.............................................................................................................7第二章相关软件介绍........................................................................................................82.13DSMAX软件介绍............................................................................................................82.2HYPERMESH软件介绍.........................................................................................................82.3ANSYS软件简介................................................................................................................9第三章液压油泵虚拟装配.............................................................................................103.1虚拟现实技术与虚拟装配简介...................................................................................103.1.1虚拟现实技术...........................................................................................................103.1.2虚拟装配...................................................................................................................103.2虚拟装配的方案和步骤...............................................................................................113.2.1液压油泵泵轴装置装配顺序...................................................................................113.2.2装配动画的具体步骤...............................................................................................113.2.3动画生成...................................................................................................................143.3液压油泵虚拟装配总结...............................................................................................15第四章液压油泵的轴有限元分析..............................................................................164.1有限元基本理论简介...................................................................................................164.2有限元分析基本步骤...................................................................................................174.3液压油泵的轴有限元分析主要步骤...........................................................................174.3.1有限元网格的创建...................................................................................................174.3.2刚性单元的创建.....................................................................
