摘要

摘要参数建模的新范式在拉紧（或拉伸）结构的分析和设计系统的发展中被证明是有前景的。在这一前提下，所提出的工作包括在参数化建模的背景下，使用VPL（可视化编程语言）开发用于计算机辅助设计（CAE）和计算机辅助工程（CAE）集成的形式设计工具。在实现中使用的方法是力密度法（FDM）和自然力密度方法（NFDM），利用所提供的线性求解方法，适用于快速找形计算程序。该程序是作为Grasshopper插件实现的，它被命名为BATS（Taut结构的基本分析），它可以为形状查找定义边界条件的参数。介绍了用于张紧结构找形的程序结构和其他可用Grasshopper插件的基准测试，表明使用BATS具有相当优越的性能。

An overview of the natural force density method and its implementation on an efficient parametric computational framework

Abstract The new paradigms of parametric modelling have been proving promising on the advance of systems for analysis and design of taut (or tensile) structures. With this premise, the presented work consist on the development with a form-finding tool for Computer Aided Design(CAE) and Computer Aided Engineering (CAE) integration using VPL (Visual Programming Language), in the context of parametric modelling. The methods used in the implementation are the Force Density Method (FDM) and the Natural Force Density Method (NFDM), taking advantage of the linear solution approach provided, suitable for fast form-finding computational procedures. The program is implemented as a Grasshopper plug-in and it is named BATS (Basic Analysis of Taut Structures), which enables parametric definition of boundary conditions for the form-finding. The program structure and benchmarks with other available Grasshopper plug-ins for taut structures form-finding are presented, showing considerably superior performance using BATS.

期刊介绍： The aim of Curved and Layered Structures is to become a premier source of knowledge and a worldwide-recognized platform of research and knowledge exchange for scientists of different disciplinary origins and backgrounds (e.g., civil, mechanical, marine, aerospace engineers and architects). The journal publishes research papers from a broad range of topics and approaches including structural mechanics, computational mechanics, engineering structures, architectural design, wind engineering, aerospace engineering, naval engineering, structural stability, structural dynamics, structural stability/reliability, experimental modeling and smart structures. Therefore, the Journal accepts both theoretical and applied contributions in all subfields of structural mechanics as long as they contribute in a broad sense to the core theme.
