The Computational Design and Fabrication of Reciprocal Systems with Negative Gauss Curvature
摘要
Abstract
This paper innovatively presents a computational workflow for design and fabrication of reciprocal systems.The proposed method integrates parametric modeling,structural analysis and optimization,digital processing and construction,and includes the following steps.Firstly,it uses parametric modeling to obtain the initial grid.Secondly,mechanical analysis is performed and genetic algorithm is introduced to optimize the parameters with mass and strain energy as the optimization objectives.Finally,the digital construction is carried out by means of techniques such as CNC cutting.The following innovations are present in this scheme.The mass-spring method is used to create the basic form of the reciprocal systems to accommodate for geometric constraints,and the simplified structural analysis and bar selection procedure is used for interactive analysis.Genetic optimization algorithm is used to optimize and select the parameters and the scheme.关键词
