| 摘要: |
| 针对复杂机械产品研发过程中几何数字样机与性能数字样机模型转换时信息丢失的问题,构建了数字样机的模型驱动体系架构,并通过解析STEP文件的组成要素,建立了基于数字样机的平台无关模型(platform independent model,PIM);提出了基于模型驱动的PIM到UG软件、到Adams软件、到Abaqus软件的平台相关模型(platform specific model,PSM)的转换方法;基于异构软件接口和脚本语言,开发了上述3个平台的模型驱动模块,并进行了实例验证。结果表明,应用模型驱动技术可实现机械数字样机专用软件之间模型信息的共享,所开发的模型驱动模块能够快速进行仿真分析并及时输出结果。 |

| Abstract: |
| Because of information loss during the conversion between a geometric digital prototype and a performance digital prototype in developing a complex mechanical product, the model-driven architecture of a digital prototype was constructed. By analyzing the constituent elements of a STEP file, the platform independent model based on the digital prototype was established. The platform specific model conversion method from the model-driven platform independent model to the UG software, the Adams software and the Abaqus software was proposed. Based on the heterogeneous software interface and the scripting language, the model-driven modules of the above three types of software were developed and verified with numerical instances. The verification results show that the use of the model-driven method can share the model information on the special software for a mechanical digital prototype and that the model-driven modules thus developed can perform the quick simulation analysis and output its results in time. |
