摘要
提出一种基于MSC.Nastran/Patran的加筋板结构有限元模型自动生成方法。方法对加筋条位置、加筋条几何尺寸、底板几何尺寸、材料物性以及网格密度完全参数化,给出标量参数、向量参数、字符参数及动态数组在PCL函数中的具体应用,载荷、约束以及材料特性全部施加于几何体以实现网格密度的自动疏密控制。实例表明,对于帽型加筋板,张角为60°时壁板位移最小。
An automatic generation method of stiffened plate structure finite element model based on MSC. Nastran/Patran is proposed. The method of reinforced bar position, stiffefer geometry, plate geometry and material properties and the mesh density of fully parameterized concrete applications are scalar pa-rameters, vector parameter, character parameter and dynamic array in the PCL function, load, and material properties of all the constraints imposed on the geometry to achieve automatic density control grid density. Take for example shows that the type of stiffened plate, angle of 60° for minimum wall displacement.
