潍坊市区道路汽车行驶工况实验研究3

I潍坊市区道路汽车行驶工况实验研究摘要车辆行驶工况主要用于车辆及发动机经济性能和排放性能的评价，其能否反映车辆及发动机在特定交通条件下的真实工况直接关系到能否对车辆及发动机的经济性能和排放性能进行合理的评价。而能否对车辆及发动机的经济性和排放性进行准确测试和合理评价，又直接影响到能否对车辆及发动机的经济性和排放性进行合理有效的优化。本文以潍坊市乘用车为研究对象，确定了潍坊市乘用车道路试验方案，对比分析国内外车辆行驶工况解析方法，确立了潍坊市乘用车行驶工况解析方法和行驶工况解析过程所应用软件，采用主成分分析和聚类分析两种高级数据处理技术，在进行道路试验的基础上，利用行程分析理论建立了能够反映潍坊市乘用车实际运行的行驶工况；然后通过特征参数值对所建立车辆行驶工况进行分析，探讨了潍坊市车辆运行状况存在的问题，以及出现这些情况的原因，同时阐述了交通信号灯对所建立行驶工况的影响；最后对比分析了潍坊工况与其他典型工况，结果发现，其他工况显然不能真实反映出潍坊的实际状况。建议采用潍坊市自身的乘用车综合行驶工况，以便制定出更科学更符合实际的乘用车污染控制对策。关键字：道路试验，行驶工况，实验研究IIABSTRACTVehicleconditionismainlyusedforevaluationofvehicleandengineofeconomicperformanceandemissionsperformance,itcanreflectthevehicleandengineinaspecifictrafficconditionsinrealworkingconditionisdirectlyrelatedtowhetherthevehicleandengineeconomicperformanceandemissionsperformanceandreasonableevaluation.Andwhetherthevehicleandenginefueleconomyandemissionsforaccuratetestingandevaluation,butalsodirectlyaffecttheabilityofvehiclesandfueleconomyandemissionofthereasonableeffectiveoptimization.Inthispaper,thepassengercarofWeifangcityastheresearchobject,thepassengercarofWeifangcityroadtestscheme,comparativeanalysisofdomesticandforeignvehicledrivingcycleanalysismethod,establishedthevehicledrivingcycleanalysismethodandanalyticprocessoftheapplicationsoftwarerunninginWeifangCity,usingprincipalcomponentanalysisandclusteranalysisoftwokindsofadvanceddataprocessingtechnology,inthebasedonthetheoreticalanalysisoftheroadtest,establishedtoreflecttheWeifangcitybydrivingcarrunningthroughstroke;thentheestablishedvehicledrivingcycleswereanalyzedthroughthecharacteristicparameter,therunningstateofthevehicleinWeifangCity,andthereasonsoftheseconditions,thetrafficsignallamptheeffectsofrunningconditions;finally,thecomparativeanalysisofWeifangandothertypicalworkingconditions,results,otherconditionsobviouslycan'treflecttherealsituationofWeifang.PassengercarcomprehensivedrivingconditionsrecommendedWeifangcityitself,inordertodeveloppassengervehiclepollutioncontrolstrategiesmorescientificandmorepractical.Keywords:running,roadtest,experimentalstudy1目录第一章绪论.....................................................................................................................................21.1引言.....................................................................................................................................21.2建立车辆行驶工况的意义.................................................................................................41.3国内外车辆行驶工况研究现状分析.................................................................................51.3.1国外车辆行驶工况研究现状..................................................................................51.3.2国内车辆行驶工况研究现状..................................................................................91.4本论文的主要内容...........................................................................................................11第二章潍坊市交通状况分析及工况解析方法的确立...............................................................112.1潍坊市交通特征概括.......................................................................................................112.1.1潍坊市道路状况概括............................................................................................112.1.2潍坊市总体交通特征分析....................................................................................122.2车辆行驶工况建立方法的对比分析...............................................................................132.2.1行驶工况的类型....................................................................................................132.2.2车辆行驶工况解析方法讨论................................................................................142.2.3潍坊市区乘用车行驶工况解析方法的确定........................................................16第三章潍坊市车辆行驶工况开发...............................................................................................183.1开发实验的选取...............................................................................................................183.1.1试验方法的选取....................................................................................................183.1.2试验道路的选择....................................................................................................203.1.3测试用车以及测试人员的选择............................................................................213.1.4试验的确定............................................................................................................223.2测试实验信息采集...........................................................................................................223.2.1数据的设置与采样间隔........................................................................................223.2.2数据量的确定........................................................................................................243.2.3数据采集方式的选择............................................................................................253.3工况形成过程...................................................................................................................263.4潍坊市车辆行驶工况的建立...........................................................................
