摘要:

受折纸启发的自展开结构具有轻质、紧凑和自主展开的能力,使其在航空航天和国防应用中极具吸引力,例如太阳能电池板、天线和反射器系统。本文提出了在ABAQUS中模拟Miura折纸单元的有限元框架,重点研究了两种展开机制:弹性应变能释放和热激活形状记忆聚合物(SMPs)。针对弹性展开的实验数据验证表明,该模型能够准确捕捉折叠轨迹和整体运动学。参数化研究揭示了铰链刚度和阻尼对展开效率的影响。基于SMP的模拟定性地再现了应力-应变-温度行为和真实的形状恢复率。该研究证实,预测性数值模型可以有效指导基于折纸的可展开结构在航空航天和国防应用中的设计,同时强调了与铰链建模、阻尼效应和热机械驱动相关的挑战。

英文摘要:

Origami-inspired self-deployable structures offer lightweight, compact, and autonomous deployment capabilities, making them highly attractive for aerospace and defence applications, such as solar panels, antennas, and reflector systems. This paper presents finite element frameworks for simulating Miura-origami units in ABAQUS, focusing on two deployment mechanisms: elastic strain energy release and thermally activated shape-memory polymers (SMPs). Validation against experimental data for elastic deployment demonstrates that the model accurately captures fold trajectories and overall kinematics. Parametric studies reveal the influence of hinge stiffness and damping on deployment efficiency. SMP-based simulations qualitatively reproduce stress-strain-temperature behaviour and realistic shape recovery ratios. The study establishes that predictive numerical models can effectively guide the design of origami-based deployable structures for aerospace and defence applications, while highlighting the challenges associated with hinge modelling, damping effects, and thermomechanical actuation.
