摘　　要：复杂产品设计具有反复性、试探性、选择性等特点,其间产生的大量关系复杂、类型各异的科学数据的组织与管理已成为影响设计性能的一个瓶颈问题。对此,在分析归纳基于科学计算的工程设计特点的基础上,引入了描述设计对象属性及相关业务处理逻辑的业务构件概念,采用了"关系数据库+原始文件+XML Schema"的数据存储方式,提出了基于构件和项目版本的网状版本关系模型,以实现对过程数据和阶段数据进行分别管理,给出了版本合并及可视化等关键技术的实现方式。最后,以航空发动机涡轮设计为例进行了验证。Scientific computing in complex product engineering design process was characterized by its tentativeness and iteration,which produced large-scale phases data with different formats and complex relationships,it became a bottleneck of product design performance for efficient organization and management of those data.To deal with this problem,based on the characteristics analysis of scientific computing in engineering design,concept of business component describing the design object′s properties and corresponding processing logics was defined to deal with the complex data management problems.Considering the diversity of data formats,a combined data storage mode was adopted for different data,i.e.RDB＋Plain File＋XML Schema,and a net version model was designed based on object version and project version to implement the management of process data and phase data respectively.Furthermore,implementation of key technologies such as version mergence and visualization were also discussed.Finally,an example illustration was given in aero-engine turbine design to verify the efficiency of the proposed method.
