<p><P>PROBLEM TO BE SOLVED: To provide a simulation method for deformation of a membrane structure which is advantageous in accurately reproducing deformation behavior of a membrane structure while suppressing a cost. <P>SOLUTION: Shape data D1 representing the shape of a membrane structure 30 is provided to an analyzing means 10B. The analyzing means 10B element-divides the membrane structure 30 based on the shape data D1 to generate structure data. Then, material characteristics data D2 representing material characteristics of a membrane 32 is set to the analyzing means 10B. A material characteristics setting step includes an additive mass addition step in which a mass per unit area of the fluid contacting the membrane 32 is added as an additive mass to the density specified by the material constituting the membrane 32, and a resultant value is set as a density of the membrane 32. Then, constraint condition data D3 and pressure data D4 are set to the analyzing means 10B. The analyzing means 10B performs calculation by a finite element method based on the data set thereto, and outputs data D10 representing a deformation behavior of the membrane structure 30. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
