汽车起重机主臂的设计VIP免费

沈阳理工大学学士学位论文摘要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，市场汽车起重机的需求也随之增加。本文通过对徐工50吨汽车起重机主臂进行研究，进一步进行主臂设计，通过计算对主臂的三铰点、主臂的长度、及每节臂的长度、液压缸尺寸进行确定，选择零部件，确定主臂伸缩方式及主臂内钢丝绳的缠绕方法，通过SOLIDWORKS软件对主臂进行三维建模。关键词：50吨汽车起重机、主臂设计、三铰点、伸缩方式、三维建模I沈阳理工大学学士学位论文AbstractWiththerapiddevelopmentofeconomicconstruction,China'sinfrastructureisgraduallyincreasetheintensity,roadtraffic,airports,ports,waterconservancyandhydropower,municipalconstructionofinfrastructuresuchasthescaleofconstructionisalsogrowing,cranetruckcranemarketdemandwiththeincrease.BasedontheXuGong50tonsoftruckcraneboomstudy,furtherboomdesign,bycalculatingthemainarmofthethreehinges,themainarmlength,andthelengthofeacharm,hydrauliccylindersizeidentify,selectPartsandcomponents,identifythemaintelescopicarmandtheboominthewayofwindingropemethod,SOLIDWORKSsoftwareonthemainarmforthree-dimensionalmodeling.Keywords:50-tontruckcrane，theboomdesign，thethreehingepoints，stretching，three-dimensionalmodelingII沈阳理工大学学士学位论文目录摘要..........................................................IABSTRATE.......................................................II1绪论........................................................11.1起重机械的工作特点及其在国民经济中的作用....................................................................................11.2国内汽车起重机的发展概况和发展趋势..................................................................................................21.2.1国内汽车起重机的发展概况......................................................................................................................21.2.2国内汽车起重机发展趋势..........................................................................................................................31.3国外汽车起重机发展概况及发展趋势.......................................................................................................41.3.1国外汽车起重机发展概况..........................................................................................................................41.3.2国外汽车起重机发展趋势..........................................................................................................................51.4SOLIDWORKS软件的介绍.....................................................................................................................................61.5本课题内容及重要意义....................................................................................................................................7250吨汽车式起重机的主要技术参数和工作级别............................82.150吨汽车式起重机的主要技术参数...........................................................................................................82.250吨汽车起重机的工作级别.......................................................................................................................10350吨汽车起重机主臂尺寸的确定.....................................133.1吊臂跟部铰点位置的确定.............................................................................................................................13III沈阳理工大...
