摘要
着重讨论用动力松驰法获得预张力膜结构的最小曲面 ;剖析了动力松驰法的内核 ,并分析了该方法用于膜结构中的具体细节。通过采用“运动阻尼”的思想 ,使得该方法更为简便、有效。
This paper stressed on stable minimal surface in form finding of prestressed membrane structures by means of Dynamic Relaxation (D.R.).The working process of D.R.has been deeply studied,and the details of its application in membrane structure has been given.The method is for more simplified by adopting an efficient concept of kinetic damping.The paper ends with the presentation of two examples.
