摘要
提出一种改进的动力松弛法 ,用于对索网结构进行形状确定。同经典的动力松弛法相比 ,它的计算效率更高 ,适用范围更广 ,可用来分析短程线型、均匀网格型和柔性边界型索网的形状确定问题。另外 ,改进的动力松弛法的有关参数 。
A new method for the form finding of cable nets is proposed in the paper.It is called as the modified dynamic relaxation.The method is verified by some benchmark problems and big projects.The results of the proposed method are compared with that of the ordinary.Numerical examples show that the modified method can be used to find the shape of various cable nets.It includes such as the geodesic networks,uniform mesh nets,and networks with flexible boundary.There are some useful conclusions are obtained through the study.
