具有形态适应性的flasher折纸模型构型设计方法OA北大核心

Based on the study of geometric relations in the classical origami flashers,an approach to designing origami flashers with shape accommodation is proposed in response to the issues of the classic origami flashers with a single form of folding,and lack of adjustability and adaptability.The methods of establishing mathematical models and theoretical derivation are used to achieve the adjustment of folding height and folding-unfolding curvature of the flasher origami model,and numerical simulations and experiments are also carried out.The results show that this approach not only lowers the flasher model's folding height,but also modifies the folding-unfolding curvature of the flasher model,which significantly enhances the adaptability and flexibility of origami flashers.The novel crease design approach of origami flashers facilitates their potential applicability in large space engineering applications and deployable mechanisms.
