Abstract
En 中文
The advancement of digital fabrication technologies and computational design has expanded the possibilities in architecture and construction. These technologies enable the creation of innovative structures and the exploration of non-standard materials, resulting in a new understanding of the design process and the development of advanced digital tools. Among these innovations, coreless filament winding, a robotic fabrication process, has facilitated new applications of fiber-polymer composites in architecture over the past decade. Coreless wound structures are characterized by a sequential and emergent nature, where the final geometry is shaped by material behavior. As a result, these structures are inherently difficult to predict, requiring constant feedback between digital models and physical prototypes due to the limited availability of fast, accessible simulation methods. This paper presents a simulation method developed to address this gap by supporting the early design stage of coreless wound fiber structures. The method incorporates relevant design and fabrication parameters while maintaining a necessary level of abstraction to ensure efficiency and accessibility. A case study was conducted to evaluate the simulation’s accuracy and examine the influence of different parameters on the final geometry. The study benchmarks a set of digitally simulated fiber specimens against their physical counterparts. The physical behavior of the fiber elements was captured using a monitoring method that scans the structure after each fiber segment is wound, enabling the observation of material behavior throughout the process. The results demonstrate the method’s efficacy, showing an average displacement deviation of -20 mm and high precision in fiber interaction, with 73% of specimens achieving 100% accuracy in generating intersection points. Furthermore, the study assesses the influence of design and fabrication parameters on fiber behavior, enabling informed decisions in early-stage design. By introducing an accessible and computationally efficient simulation method, the research aims to contribute to the field by providing efficient, early-stage feedback and an initial understanding of material behavior in coreless filament winding, while also identifying current limitations and directions for future research.
