哈尔滨工业大学本科毕业论文（设计）电动叉车传动系统匹配及性能分析摘要电动叉车驱动系统性能的好坏在很大程度上取决于驱动电机。为了满足电动叉车所要求的各项性能指标，使叉车整体的性能得到更好地发挥，对电机本身性能参数的选择非常重要。同时由于电动叉车在行驶的过程中所遇到的工况比较简单，并且所面临不同工况的阻力变化比较小，在电机和叉车的车轮之间联接上机械传动部分的变速器或固定速比减速器及主减速器，有利于减轻驱动电机及电池组的负荷，所以确定传动系统的传动比也是一个重点。本文根据电动叉车的整车参数及动力性能指标的要求，通过分析计算对驱动电机进行选型并确定了机械传动系统的传动比，使驱动电机与传动系统的参数合理匹配，有利于提高电动叉车整体的动力性能。本论文主要研究的是三支点式平衡重电动叉车传动系设计与计算，因此本论文先根据整车的基本数据初步确定驱动转向桥的初始尺寸；然后利用MATLAB绘制电机特性曲线图，通过分析电机特性曲线图对传动比进行优化，根据得到的优化尺寸利用CATIA进行三维建模；利用CATIA的工程图输出功能输出二维图到AutoCAD进行编辑。关键词电动叉车；传动系；匹配；MATLAB-I-哈尔滨工业大学本科毕业论文（设计）TransmissionofelectricforkliftmatchandperformanceanalysisAbstractTheperformanceofthedrivesystemofelectricforkliftdependslargelyonthedrivingmotor.Inordertomeettherequirementsofthevariousperformanceindexofelectricforklifttoimproveitsoverallperformance,choosingappropriateparametersisveryimportanttothedrivingmotor.Itisnecessarytoconnectatransmissionoramainreducerassemblytodecreasetheloadofthemotorandthebatterysourcebetweenthemotorandwheelsbecauseofthesimpleworkingconditionsandthelittleresistancechangefacedwhiletheforkliftisrunning.sothecalculationoftransmissionratioisanotherkeypoint.ThearticlechoosedappropriateparametersforthedrivingmotoranddesignedthetransmissionratiotomatchtheparametersbetweentheDrivingMotorandtheTransmissionSystembyanalysisandcalculation.Meanwhile,itcanhelptoimprovetheoveralldynamicperformanceoftheelectricforklift.Thisthesisistodesignandcalculatethree-wheeledelectric-II-哈尔滨工业大学本科毕业论文（设计）forklift’stransmissionsystem.soatthebeginningthispaperdeterminetheinitialsizeofthetransmissionsystemaccordingtothedataofthisforklift,thenuseMATLABsoftwaredrawingthemotorcharacteristiccurve，Byanalyzingthecharacteristiccurveofthemotortooptimizethetransmissionratio.Aftergettingtheoptimizeddata,IuseCATIAsoftwaretobuild3Dmode,then,forediting2Dengineeringdrawing,thequalifiedmodelisoutputintothesoftwareofAutoCADbytheCATIA’sengineeringgraphicsoutputfunction.KeyWordsElectricforklift,Transmissionsystem,Matching,MATLAB目录摘要..........................................................................................................IAbstract.....................................................................................................................II第1章绪论...................................................................................11.1课题研究目的和意义.............................................11.2国内外研究现状概述.............................................11.3本文主要研究内容.....................................................2第2章三支点式平衡重电动叉车传动系概述.........................................................................................................................32.1电动叉车传动系统概述......................................32.2电动叉车动力传动系统布置形式选择......................................................................................
