Abstract

The lightweight structure system is an effort to optimize the structure to distribute the load efficiently. Unfortunately, students often have difficulty imagining the learning outcomes application in the real world when studying light structural systems. However, the use of the scalar model can still explain several essential aspects of a lightweight structural system, one of which is the effect of connection and formation of material components on the structural capability. Therefore, this paper aims to bridge the learning process by utilizing digital devices from the concept stage of structural modeling with the help of software (Rhinoceros, Grasshopper, and Kangaroo) to the realization process using laser cutting. The method used is a semi-experimental method that applies Hooke's law principle, which produces a shell structure system with a digital fabrication approach that utilizes a lightweight material, namely, corrugated paper board, as the primary material. This paper concludes that digital technology and digital fabrication processes can help students understand the concept of lightweight structures because they can use computer simulations, cut them using laser cutting, and assemble them in the field in a series of simultaneous processes.

数字化制造作为轻量化结构的学习媒介,以壳结构为例
轻量化结构体系是对结构进行优化以有效分配荷载的一种努力。不幸的是,学生在学习轻结构体系时,往往难以想象学习成果在现实世界中的应用。然而,使用标量模型仍然可以解释轻量化结构系统的几个基本方面,其中之一是材料部件的连接和形成对结构能力的影响。因此,本文旨在利用数字设备将学习过程从借助软件(Rhinoceros, Grasshopper, and Kangaroo)进行结构建模的概念阶段连接到使用激光切割的实现过程。所使用的方法是一种半实验方法,应用胡克定律原理,利用轻质材料即瓦楞纸板作为主要材料,采用数字制造方法生产外壳结构系统。本文的结论是,数字技术和数字制造工艺可以帮助学生理解轻量化结构的概念,因为他们可以使用计算机模拟,使用激光切割切割,并在现场进行一系列同步加工组装。
