摘　　要：为了获取我国主要车型的碰撞载荷特征,以某次汽车—测力墙碰撞试验的数据为基础,利用基于E-R模型的设计方法,采用Microsoft SQL Server 2005作为数据库管理系统,建立了汽车碰撞载荷数据库.在MathWorks MATLAB R2010a平台上,利用GUI设计工具以及MAT-LAB编程语言开发出了通过使用ODBC连接访问数据库的应用程序.并通过应用程序提取并分析了某次试验中的撞击力大小、撞击力分布以及撞击力高度等碰撞载荷特征,为汽车的耐撞性及相容性研究奠定了基础.In order to obtain the crash load characteristics of China＇ s major cars, an automobile crash load database was established in this paper based on the raw data of a Car - LCW（ Load Cell Wall） crash test, using ER model - based design method and Microsoft SQL Server 2005 as DBMS. A package of application pro- gram, using ODBC connection to access the database, was developed by GUI design tools and MATLAB pro- gramming language on the platform of MathWorks MATLAB R2010a. Using application program to access a set of test data in the database, the crash load characteristics of this test, such as the size, distribution and height of the impact force, was extracted and analyzed, which laid the foundation for the research of car crashworthiness and compatibiliw.
