**大学学士学位论文1汽车密封条C6工位工序动作平衡与仿真摘要本文是对北京万源瀚德汽车密封系统有限公司长春分公司audiC6工位的实习考察的基础上，获取原始资料，在排好各工艺流程内容的基础之上，运用模特法对生产线每个工位的操作动作进行分析，以确定各操作单元的操作时间。同时，根据实际情况确定出生产线的节拍，结合操作时间和节拍确定生产线平衡率.通过对生产线进行平衡并利用“5W1H”提问法以及“ECRS”原则对生产线进行适当的改进并完成C6工位工序动作平衡的设计任务。本文利用Flexsim这一软件工具对C6工位的运行过程进行了仿真，找出了在生产线运行过程中出现的阻塞和等待问题并对此进行了分析.关键词：生产线平衡，MOD，仿真，节拍**大学学士学位论文2AbstractThisarticleisHaldexBeijingWanYuanChangchunAutomotiveSealingSystemsCo.,Ltd.BranchaudiC6inspectionstationonthebasisoftheinternshiptoobtaintheoriginalinformationcontentinthelineuponthebasisoftheprocess,theuseofmodellawsontheproductionlineforeachworkbitoperatingmovementswereanalyzedtodeterminetheoperatingunit'soperatingtime.Meanwhile,accordingtotheactualsituationtodeterminetheproductionlinetothebeat,combinedwithoperatingtimeandbeattodeterminelinebalancerate,throughtheproductionlinestobalanceanduseof5W1Hquestionslaw,andECRSprincipleofproductionappropriatetoimproveandcompletetheC6-positionprocessActionbalanceddesigntasks.Inthispaper,thesoftwaretoolFlexsimC6-positionofrunningthesimulation,identifiedduringtheoperationoftheproductionlineblockingandwaitingforproblemstooccur,andthisisanalyzed.Keywords:linebalancing,MOD,simulation,beat**大学学士学位论文3目录1绪论............................................................................................................................11.1课题研究背景....................................................................................................11.2当前汽车密封条的发展形势............................................................................11.3汽车密封条的生产工艺....................................................................................21.4实习公司简介....................................................................................................21.5国外汽车密封条发展情况................................................................................32流水线及人因工程学简介........................................................................................42.1流水线的概念与特征........................................................................................42.2流水线的节拍设定及平衡率计算....................................................................52.3人因工程学........................................................................................................52.3.1人因工程概述............................................................................................52.3.2人因工程的目的........................................................................................63C6工位工序动作平衡分析设计...............................................................................13.1动作分析概述....................................................................................................13.2动作分析方法用途............................................................................................13.3模特排时法........................................................................................................23.4动作分析的应用................................................................................................43.2对各工序进行动作分析..................................................................................63.3计算工位的节拍..............................................................................................123.4计算生产线平衡率..........................................................................................134C6工位生产线动作平衡分析改善...........................................................................14.1C6工位问题分析...............................................................................................14.2C6工位改善方案...............................................................................................14.3C6工位节拍的计算...........................................................................................54.4C6工位改善后平衡率的计算：.......................................................................55基于FLEXSIM的生产线仿真....................................................................................65.1仿真软件概述....................................................................................................65.2FLEXSIM仿真软件简介.....................................................................................6**大学学士学位论文45.3FLEXSIM的主要特性.........................................................................................65.4FLIESIM软件特点.............................................................................................75.5C6工位生产线改进前后的仿真分析...............................................................76结论..........................................................................................................................12致谢..............................................................................................................................13参考文献......................................................................................................................13**大学学士学位论文11绪论1.1课题研究背景汽车密封条是汽车的重要零部件之一，广泛用于车门、车窗、车身、座椅、天窗、发动机箱和后备箱等部位，具有防水、密封及节能的重要作用，隔音、防尘、防冻、保暖。它必须具有很强的拉伸强度，良好的弹性，还需要比较好的耐温性和耐老化性。为了保证胶条与型材的紧固，胶条的断面结构尺寸必须与型材匹配。其特点：汽车用密封条主要是由具有良好弹性和抗压缩变形、耐老化、臭氧、化学作用、较宽的使用温度范围（-40℃~+120℃）的三元乙丙橡胶(EPDM)橡胶发泡与密实
