多功能清雪车总体布置设计(机械CAD图纸)

精选资料可修改编辑摘要本设计为多功能清雪车，能够清除浮雪、厚雪、薄冰、轧实的冰雪，可有效清除0～25cm厚浮雪和0～10cm厚的轧实冰雪，达到见黑路面效果。可广泛用于市政道路、高速公路、普通公路、机场等地。多功能清雪车以中国一汽生产的CA3253P7K2T1AE型卡车为行走系统，以一汽解放汽车有限公司无锡柴油机厂生产的BF6M1013-28E3/BF6M1013-26E3发动机为作业系统的驱动装置，将除雪机构与其底盘车架连接，并对除雪车的雪铲、扫雪排、撒布机机构进行结构参数设计，分析了雪铲的工作阻力，通过对冰雪力学性质、整车性能匹配的研究，提出设计方案。本文的主要工作如下：（1）调研分析机械清雪的重要性能及可行性。结合国内外目前的研究状况，明确清雪机械的发展趋势，确定研究方向。（2）研究积雪的物理机械性能。（3）铲车型号的选择及铲的设计。确定铲的参数，选择适合型号车。（4）整车受力及积雪的运动分析。计算清雪车在作业过程中整车的受力情况，分析各参数对清雪作业的影响；通过对雪单元体的研究，分析铲雪作业时的积雪运动。（5）稳定性分析。铲的特殊位置决定了其在作业过程中突出的稳定性精选资料可修改编辑问题。铲对清雪车作业稳定性的影响较大，为保证清雪车安全作业。关键词：除雪铲；撒布机构；扫雪排；滚雪刷；轨道升降机构精选资料可修改编辑AbstractThisdesignforthemulti-purposeclearsleighs,caneliminatefloatsthesnow,theglazedfrost,rollsoverthesolidsnowandice,buteliminates0~25cmtofloatthesnowand0~10cmthickeffectivelythickrollsoverthesolidsnowandice,achievedseestheblackroadsurfaceeffect.Butwidelyusesinplacessuchasmunicipaladministrationpath,highway,commonfreeway,airport.ThisarticletakeaChinesesteamproductionCA3253P7K2T1AEtruckastheundercarriagesystem,iftakeasteamliberationautomobilelimitedcompanyWuxidieselengineplantproductionBF6M1013-28E3/BF6M1013-26E3engineastheworksystemdrive,willremovesnowtheorganizationthechassisframeconnection,andwillcarryonthedesignparameterdesigntothesnowremovalbreakerconstruction,hasanalyzedtherollercompactiongunworkingresistance,throughtothesnowandicemechanicalproperties,thebreakerconstruction,theentirevehicleperformancematchresearch,willproposetheimprovementprogram.Keywords:shovelsnowremovalAndclothinstitutionssweeprow精选资料可修改编辑rollingsnowbrushrailliftingmechanism目录摘要................................................................................................IAbstract.............................................................................................III第1章绪论.......................................................................................11.1研究的目的及意义................................................................11.2国内外研究现状和发展趋势.................................................3精选资料可修改编辑1.2.1路面除冰技术的发展历程....................................................31.2.2国外路面除冰设备的研究现状............................................71.2.3国内路面除冰设备的研究现状............................................81.2.4路面除冰雪技术的发展趋势..............................................111.3本章小结............................................................................12第2章路面压实冰雪物理力学性质..................................................132.1冰雪的成因与分类..............................................................132.1.1路面冰雪分类.......................................................................132.1.2路面压实冰雪的成因...........................................................142.1.3影响因素................................................................................152.2路面压实冰雪力学性质.......................................................182.2.1抗压强度................................................................................182.2.2抗切强度................................................................................192.2.3相关系数................................................................................202.3压实冰雪破坏准则..............................................................222.4本章小结............................................................................26第3章清雪车分类及特点................................................................273.1清雪车分类........................................................................273.1.1按工作装置特点分类...........................................................27精选资料可修改编辑3.1.2按整车特点分类...................................................................313.2本章小结............................................................................32第4章前雪铲板空间曲面设计.........................................................334.1清雪铲前铲设计.................................................................334.2清雪铲铲板曲面结构参数确定............................................374.2.1推雪铲设计...........................................................................374.2.2独立壁障装置设计...............................................................424.3本章小结............................................................................44第5章清雪车部件设计...................................................................455.1滚雪刷设计........................................................................455.1.1卧式滚扫刷刷毛排布形式分类..........................................455.1.2整滚刷安装位置不同分类..................................................475.1.3按滚刷驱动分类...................................................................485.1.4整滚刷刷毛选择...................................................................495.2扫雪排设计........................................................................515.3撒布机设计........................................................................525.4油路设计............................................................................545.5本章小结............................................................................56第6章整车受力分析.......................................................................57精选资料可修改编辑6.1清雪铲受力分析.....................
