【摘要】:纵横向不等厚竹编遮阳板由横条厚竹条与纵条薄竹条组成,不仅能够有效遮挡直射太阳辐射,减少制冷能耗,同时可以允许充足的漫射光透射进入室内,从而保持良好均衡的室内光环境,是一种节能可持续的理想遮阳板。通过对4种尺寸的该类竹编遮阳板分别建立有限元模型,对不同风速和不同风攻角下遮阳板结构的力学性能进行数值模拟仿真。计算结果表明,1m×1m、1.5m×1.5m、3m×1m三种结构均能满足刚度要求,而3m×3m结构由于变形量过大不能满足刚度要求,建议采用1m×1m或1.5m×1.5m或3m×1m结构进行组合。由于竹材具有良好的力学性能,各尺寸结构均能满足强度要求。该研究成果可为该类竹编遮阳板设计和使用参考。
[Abstract]:The bamboo shading board with different vertical and horizontal thickness consists of thick and vertical bamboo strips, which can not only effectively block direct solar radiation and reduce cooling energy consumption, but also allow sufficient diffuse light to be transmitted into the room. Therefore, it is an ideal and sustainable sun shading board to maintain a good and balanced indoor light environment. The finite element models of four kinds of bamboo shading boards were established, and the mechanical properties of the shading board structures with different wind speeds and different angles of attack were simulated numerically. The calculation results show that the three kinds of structures can meet the stiffness requirements, while the 3m 脳 3m structures can not meet the stiffness requirements due to excessive deformation. Therefore, it is suggested to adopt the combination of 1m 脳 1m or 1.5m 脳 1.5m or 3m 脳 1m structures. Due to the good mechanical properties of bamboo, each size structure can meet the strength requirements. The research results can be used as reference for the design and use of bamboo-woven shading boards.
