毕业设计（论文）车辆火灾聚类分析.docxVIP

摘 要随着汽车保有量的不断增加，出现的汽车事故也越来越多，汽车火灾事故的数量也在随之增长，汽车起火之前，不易被察觉，起火之后，火焰蔓延迅速，火势凶猛，很难扑救。汽车火灾事故一旦发生，势必会造成或多或少的经济损失，还极可能造成人员伤亡，因此对汽车火灾事故进行聚类分析，区分汽车火灾事故类别，分析起火原因，对预防和避免汽车起火很有帮助。对于汽车火灾事故的聚类分析，要保证分析结果的准确可靠，需要获得真实的数据，因此从长安大学机动车物证司法鉴定中心进行数据调研，调研之前对调研内容和调研表格进行思考与设计，获得调研数据之后，先采取简单的统计方法对数据进行统计分析，分析结果说明了汽车火灾事故涉及各种车辆，起火原因复杂，且近几年自燃事故多发，对汽车火灾事故的聚类分析有一定帮助。为了进行汽车火灾事故的聚类分析，将所有起火原因进行细分，并将调研数据赋值变为数值变量，通过SPSS统计分析软件进行聚类分析，得到聚类的图表结果，对图表结果进行分析，结果实际情况和实际需要，将汽车火灾事故合理的分类。汽车火灾事故的相关研究较少，因此要对汽车火灾事故的聚类分析结果进行具体的分析和说明，结合调研具体事故案例，对每一种汽车火灾事故类别进行分析，对于针对性的预防此类事故发生和有效的避免此类事故具有重要意义。关键词：汽车火灾，聚类分析，自燃，统计ABSTRACTWith the increase in car ownership, the emergence of more and more car accidents, the number of car fires also increased, the car before the fire, not easy to detect, after the fire, the rapid spread of the fire, ferocious fire, it is difficult Save. Car fire accident in the event, it is bound to cause more or less economic losses, but also likely to cause casualties, so the car fire accident cluster analysis, distinguish between car fire accident category, analysis of fire causes, to prevent and avoid the car fire Very helpful.?For the vehicle fire accident cluster analysis, to ensure accurate and reliable analysis of the results, the need to obtain real data, so from the Changan University Vehicle Certification Center for data research, research before the research content and research forms to think and design, After obtaining the research data, the statistical analysis method is used to analyze the data. The analysis results show that the automobile fire accident involves various vehicles, the cause of the fire is complicated, and the spontaneous combustion accident occurs in recent years. The cluster analysis of the automobile fire accident has Must help.In order to analyze the cause of automobile fire accident, all the causes of fire were subdivided and the value of the survey data was changed into numerical variables. Cluster analysis was carried out by SPSS statistical analysis software to obtain th
