摘要
结合"大飞机"项目启动所必须的关键设备800MN巨型模锻压机,对大型组合结构整体有限元建模进行深入研究和分析,对此类结构在建模过程中单元类型的选取、单元网格的划分规则和摩擦模型的选取等问题进行详细分析和仿真试验,得出建立这类大型组合结构需遵循的相应原则,使模拟仿真结果更趋于真实,分析结果为大型组合结构的有限元建模分析提供了理论依据和数据支持。
800MN forging presses is the necessary key equipment as＂ big aircraft＂ project to start, the structure of the overall portfolio of large finite element modeling conducted in-depth research and analysis, modeling of such structures in the process of selection of unit types, unit division of the grid rules, friction model selection issues such as a detailed analysis and simulation tests, come to set up such a large-scale composite structures to be followed in the corresponding principle, so that simulation results become more real, the results of the analysis of composite structures for large-scale finite element modeling analysis provides a theo- retical basis and data support.
