A Study of Form-Finding Methods for Membrane Structure by Nonlinear Finite Element
【摘要】 对基于非线性有限元法的两种膜结构找形方法(支座移动法和节点平衡法)进行了分析,在此基础上提出了节点定向移动法。通过计算实例表明,该方法具有更快的收敛速度和更高的计算精度,是一种实用的找形分析方法。
【Abstract】 Two kinds of form-finding methods based on nonlinear finite element, support-moving method and joint-equivalence method, are introduced and examined. By taking into account the advantages of the two methods and the characteristic of form-findings, a joint-directed moving method is presented. The numerical results show that the new method convergence more rapidly with more accurate precision, so it can be used practically.
