沈阳建筑大学毕业设计摘要在我国，汽车起重机发展已有六十多年的历史了，由于受到客观条件的限制，一度发展较慢，进入九十年代发展迅速，但与国际先进水平还相差很远，主要表现在产品质量的稳定性，自动化，智能化等方面。随着经济建设的迅速发展，我国的基础建设力度正逐渐加大，道路交通，机场，港口，水利水电，市政建设等基础设施的建设规模也越来越大，汽车起重机的市场需求也随之增加。本文是对QY16U型汽车起重机的吊臂伸缩机构进行设计，确定吊臂主要尺寸、质量参数，确定各部件、总成的相互位置关系，利用Solidworks完成QY16U汽车起重机吊臂伸缩机构的三维实体装配模型，利用Ansys对结构件进行强度校核，对确定中、小型汽车起重机的设计方案具有很强的现实意义。关键词：汽车起重机；吊臂；伸缩机构ABSTRACTThedesignandproductionofthetruckcranehavemorethan50year’shistoryinourcountry.Thedevelopmentoftruckcrane,however,hassloweddownforsomeobjective1沈阳建筑大学毕业设计reasons.Since1990’s,itwasacceleratedinourcountry,buttheproductsstillcouldnotreachtheadvancedinternationallevelinthequalitystability,autnation,andintelligent.Withtherapiddevelopmentofeconomicconstruction,China'sinfrastructureisgraduallyimprovingtheintensity.Roadtraffic,airports,ports,waterconservancyandhydropower,municipalconstructionofinfrastructuresuchasthescaleofconstructionisalsorapidlygrowing.Cranetruckcranemarketisalsoondemandwiththeincrease.ThethesisisthestudyofthetypeoftruckcraneQY16UdesignandthediscourseuponchoicesofTelescopiccraneagency.Theoveralllayoutandstability,thedesignoftheliftingmechanismandcalculationmethods.Itisalsodiscussedchieflyconcernswithhowtodeterminethewholemachinesize,qualityparameters,andhowtodeterminethecomponents,assemblylocationofthemutualrelations.TheusingofSolidworkstocompletetheQY16Utelescopiccraneagencyofthree-dimensionalsolidmodel,andtheusingofAnsystoanalysethestrengthofstructural,haveastrongpracticalsignificancetoidentifythesmallandmedium-sizedtruckcranedesign.Keywords:truckcrane；Telescopic；craneagency目录第一章绪论...............................................................12沈阳建筑大学毕业设计1.1概论..................................................................11.2汽车起重机的发展趋势..................................................11.2.1广泛采用液压技术....................................................11.2.2通用与专用起重机....................................................21.2.3重视“三化”逐步过渡采用国际化标准..................................21.2.4发展一机多用产品.....................................................21.2.5采用新技术、新材料、新结构、新工艺...................................31.2.6国外汽车起重机发展过程及主要机种.....................................31.3汽车起重机现代设计方法概述............................................41.3.1汽车起重机现代设计方法概述计算机辅助设计（CAD）.....................51.3.2模块化设计..........................................................51.3.3有限元设计..........................................................51.3.4优化设计.............................................................51.3.5动态仿真设计.........................................................51.4课题背景..............................................................61.5课题任务..............................................................7第二章吊臂技术参数的确定.................................................82.1吊臂主要性能参数......................................................82.2QY16U型...
