机械产品仿真数据提取技术研究

实现多源仿真数据的协同可视化是产品设计师洞察所设计产品性能的有效途径,针对目前对仿真数据的查看都是基于与商用软件的交互操作来实现的,提出了应用于异构机械产品性能分析仿真软件的数据提取方案。通过研究仿真软件的数据提取方法、固有的数据格式及二进制文件的解析方法,定义了一种可以兼容各种仿真分析数据的统一数据格式,重点研究了统一数据模型的建立及框架结构的设计,论述了数据提取的流程,最后通过Ansys和Abaqus结果文件的数据提取对框架结构进行了验证,实现了在脱离商业仿真软件环境下实时查看仿真数据。

Research on Simulation Data Extraction of Mechanical Products

Realizing the multi-source simulation data collaborative visualization is the effective way for designers gaining an insight into product performance and the current view of the simulation data is mainly based on interaction with the commercial software,the simulation data extraction solution in simulation software for heterogeneous mechanical product performance analysis is presented in this paper.Through studying data extraction methods,data inherent format and the binary file,the unified data format being compatible various simulation analysis data was defined.The unified data model and the framework structure were studied.The process of data extraction was discussed.Finally the framework structure was verified by taking ansys and Abaqus results file of data extraction as an example,realized view the simulation data in real-time disengaged from the commercial simulation software environment.
