汽车发动机台架实验室的工艺设计(理想版)

如有疑问可以联系我，QQ530587040或[e-mail]毕业论文（设计）题目：汽车发动机台架实验室的工艺设计学生：林钰凯专业：车辆工程班级：车辆0501学号：0105110128指导老师：丁志刚第1页共73页摘要汽车发动机本身是一种非常复杂的精密动力机械,结构复杂,也形成了对内燃机各工作辅助系统提出较高的要求,这些都是发动机实验所要解决的基本问题.除了要有各种测量仪器设备外,还要有一个能保证实验条件尽可能接近实际使用条件和保证发动机各项参数测量精度高的实验室,同时必须把实验室的一些辅助系统设计合理.发动机台架试验可调支架，作为发动机台架试验的一个不可缺少的组成部分，其作用是支承被检测的发动机。一套可适用于不同型号发动机的可调支架，对发动机的一系列台架试验将起到重要的保障作用。本文先通过对台架基础，测功机，通风换气系统，冷却水系统，进、排气系统，燃料系统，隔振，降噪以及其他等等深入了解，而后进行基本设计。然后特别地了解有限元技术，设计出支架，并进行强度校核。接着对实验室的系统软件介绍，特别是控制装置诸如水温，油温控制装置等等。最后对实验进行简单的说明。关键词：发动机，台架基础，支架，设计，校核，实验第2页共73页AbstractAutomotiveengineitselfisaverycomplexdynamicprecisionmachineryandcomplicatedstructural,butalsocausetheformationofhighrequirementsontheworkingassistedsystemoftheinternalcombustionengine,whicharethefundamentalissuesoftheenginelaboratorytoresolve.Inadditiontoavarietyofmeasurementinstrumentsandequipment，butalsothereisalaboratoryguaranteethattheactualexperimentalconditionsareascloseaspossibletotheuseofconditionsandensuretheparametersoftheenginehavehighprecisionmeasurements,andthendesignsomerationalsupportsystemofthelaboratory.Thedesignofsuitablesupportforenginebenchexperimentisanessentialcomponent,whosefunctionissupportingtheexamedengine.Agroupofsupportswhicharesuitableforvariousmodelsofenginesplayanimportantroleinprotectingaseriesofenginebenchexperiments.Thisthesisiscarryedoutthebasicdesignbyso-depthunderstandingofbenchbasic,dynamometer,ventilationsystems,coolingwatersystems,exhaustsystem,fuelsystem,vibrationisolation,noisereductionandsoon.Andinparticularunderstandingoffiniteelementtechnology,designsupportandcheckstrength.Andthen,introducelabSystemSoftware,inparticular,controldevices,suchaswatertemperature,oiltemperaturecontroldevice,etc.Finally，theexperimentismadeoutsimply。Keywords:engine，benchbase，support，design，exam，experiment第6页共73页目录绪论......................................................................................................................................................................8第一章发动机的概述.....................................................................................................................................91.1发动机的组成........................................................................................................................................91.2发动机的发展趋势.............................................................................................................................101.2.1柴油发动机技术的发展趋势..................................................................................................101.2.2汽油机发动机技术的发展趋势..............................................................................................101.2.3我国车用发动机发展趋势分析..............................................................................................111.3发动机的工作原理.............................................................................................................................111.3.1汽油发动机的工作原理.........................................................................................................121.3.2柴油发动机的工作原理.........................................................................................................14第二章发动机台架试验.................................................................................................................................152.1台架试验的组成.................................................................................................................................152.2台架试验的简述.................................................................................................................................152.3我国发动机测试体系简述.................................................................................................................162.5发动机试验的标准.............................................................................................................................192.6几个著名的发动机试验与测试设备生产单位.................................................................................20第三章发动机台架实验室的基本设计.........................................................................................................203.1试验台架基础的要求.........................................................................................................................213.2减振和隔振.........................................................................................................................................223.3.1地平铁.......................................................................................................................................223.3.2钢筋混凝土重块......................................................................................................................223.3.3台架基础图..............................................................................................................................233.4测功机..................................................................................................................................................243.4.1电涡流测功机..............................................................................................................
