复杂桥梁结构不同软件模型转换接口开发及验证

Verification and program development of model transformation interface for complex bridge with different software

结合桥梁设计软件MIDAS civil方便高效的前处理功能和通用有限元软件ABAQUS强大的分析功能,开发了从MIDAS civil到ABAQUS软件的接口程序,该程序可以实现桥梁结构在MIDAS civil中快速建模和在ABAQUS中精确分析的目的。通过2个实例桥梁模型进行了2种软件之间的转换,对转换前后的模型信息及模态分析结果进行了对比,验证了开发程序的正确性。该项工作可以极大的提高复杂桥梁结构在ABAQUS中的建模效率。

In this paper, model transformation interface program was developed fi＇om MIDAS civil to ABAQUS, which combined the advantage of MIDAS civil with high efficiency pre-process function and ABAQUS with strong a- nalysis function. The interface can realize the aim of fast model establishment in MIDAS civil and precise analysis in ABAQUS. Finally, two practical engineering examples were used to be transformed and verified. Comparison was analyzed for the results of model information and vibration model. The result verifies the correctness of the pro- gram. This work can greatly increase the model establishment efficiency in ABAQUS for the complex bridges.
