【摘要】 STEP是关于产品生命周期中数据表达和交换的国际标准。SDAI是STEP采用的标准数据存取接口,是针对不同的数据存贮技术而提供的统一的数据存取接口标准。文章通过SDAI标准数据存取接口,来实现有限元分析本体程序和后处理系统之间的数据交换,在此基础上实现了STEP/AP209格式文件的读入,并对有限元后处理技术进行了研究。更多还原

【Abstract】 STEP is an international standard about data representation and exchange in the product’s life cycle.SDAI is the standard data access interface adopted by STEP,It aims to provide a uniform data access interface standard be-tween different systems.The data exchange between finite element analysis programs and post-processing systems is re-alized by using SDAI.The datas are read from STEP/AP209files.The technologies concerned with finite element post-processing are discussed.更多还原
