Abstract


This paper summarizes the current membrane structure commonly used cutting methods , analysis of the key issues in the membrane structure cutting , pre - tension release from the membrane structure , cutting seam design and surface flattening a series of analytical methods . A detailed analysis of the nature of the pre - release of tension membrane structure , put forward a new idea for solving dynamics method . Nonlinear dynamic finite element method is derived , and discuss its solution method , and the preparation of the analytical procedures , pre - release of tension on the membrane structure numerical example . This paper presents a simple surface simulation method , and this method is applied to the simulation of the membrane structure surface . This approach is based on dynamic relaxation method is applied in the calculation of the surface between two points on the geodesic . Under both methods , the preparation of the corresponding program , and a numerical example . The results show that the surface simulation method applicability , simple and convenient , high precision geodesic dynamic relaxation method , practical . Summary of the previous surface flattening method , with minimal deformation energy principle surface flattened Standards , were analyzed for surface flattening process , and based on the analysis prepared surface flattening procedure . The example shows that the method developable surface flattening is accurate , on a non - developable surface flattening high accuracy .
