基于UGS NX环境开发出了新一代板料成形快速仿真系统FASTAMP-NX,该系统完全集成于NX环境,避免了数据转换带来的数据损失,充分利用了NX参数化特征建模的优势,实现了真正意义上的CAD/CAE无缝集成。系统求解器基于BT壳单元模型和改进的动力显式有限元算法,计算速度较同类商业求解器提高1.5倍以上。可应用于工艺设计和模具设计阶段,协助设计人员在统一的NX环境下快速分析与校核设计方案,大大提高了设计与分析的效率,使模具设计"当天工程"成为可能。

FASTAMP-NX is the new generation of sheet metal forming analysis system,which is completely based on UGS NX environment.The finite element model can be directly transformed from CAD model in "naught distortion" without any parameterized modeling feature loss to achieve the real CAD/CAE seamless integration.The solver is based on BT shell element and updated dynamic explicit FE method and is much faster than most commercial solvers.The system can be applied to potential defects prediction and process verification as the powerful assistance analytical tool in the uniform NX environment.The efficiency of design and analysis is greatly improved to make die design "one-day-cycle" possible.
