摘要
提出一种桁架结构自动生成的方法。该方法在给定节点、外部荷载和材料属性的条件下,应用Delaunay三角剖分法实现桁架几何结构的自动生成,根据平衡矩阵的秩判断桁架几何结构的稳定性,应用满应力法对几何结构进行尺寸优化,得到满足工程需求的桁架结构。联合应用VC和MATLAB编程软件实现了桁架的自动生成与可视化。实际应用表明此方法在处理桁架结构自动生成的问题上具有可行性和有效性。
A new method of automatic generation of truss structures is proposed.Under the condition that the nodes,external load and material properties are given,this method allows the truss geometrical structure to be generated automatically by applying the Delaunay triangulation.And the stability of truss geometrical structure was judged by the rank of equilibrium matrix,the full stress method is used to optimize the dimension of the geometric structure,obtaining truss structures that can meet engineering demands.The automatic generation and visualization of truss is allowed by using VC and MATLAB programming software together.The practical applications show the method herein has feasibility and validity when solving the problems as automatic generation of the truss structure.
