摘要
提出了一类适用于大规模二维网格结构计算的离散模型.该模型以网格节点为研究对象,其控制方程仅与跟节点相连的杆件数目及几何形状有关;只要给出几种基本类型的节点控制方程,就可以对具有相应形式节点的各种规模的网格材料组合其控制方程而求解.这种离散模型形式简单,尤便于在计算机上实现.
In this paper a class of discrete models are proposed which are suitable to evaluate a variety of two-dimension lattice structures. The research object of the model is the node of lattice, and its governing equations are related to the number of bars connecting with the node and the geometry. If only some types of governing equations of essential nodes are presented, the evaluation of cellular solids can be processed for every type of lattice with a corresponding type node. The form of this model is simple and easy to carry out by computer.
