The invention discloses an expandable bidirectional winding type solar wing, belongs to the technical field of mechanical design, solves the technical problems of insufficient rigidity and lower inherent frequency of an external frame of a flexible solar wing after being expanded in the space, and adopts the technical scheme that the expandable bidirectional winding type solar wing comprises a winding system for winding and unwinding a working surface of the solar wing, and the winding system comprises a winding and unwinding mechanism and a folding chain, the winding and unwinding mechanism comprises an upper conveying roller, a lower conveying roller, a support, a motor and a framework winding drum, the folding chain comprises an upper-layer flexible thin strip, a lower-layer flexible thin strip memory alloy plate and a sealing edge, and the memory alloy plate comprises two layers of first memory alloy plates and two layers of second memory alloy plates; when the folding chain is in a rolling state, the folding chain is in a strip shape on the whole, and when the folding chain is in an unrolling state, the folding chain is in a tubular shape on the whole. A double-winding-drum unfolding mode is adopted, the folding and unfolding ratio of the working face of the solar wing can be effectively increased, stable supporting in the unwinding state is achieved through the folding chains, and the winding state is smooth and reliable.
一种可展开的双向卷绕式太阳翼,属于机械设计技术领域,解决柔性太阳翼外部框架在太空展开后刚度不足、固有频率较低的技术问题,解决方案为:本发明包括用于卷、放太阳翼工作面的卷收系统,所述卷收系统包括收放机构和折叠链条,所述收放机构包括上传送辊、下传送辊、支架、电机和骨架卷筒,所述折叠链条包括上层柔性薄带、下层柔性薄带记忆合金板以及封边,所述记忆合金板包括两层记忆合金板一和两层记忆合金板二;当折叠链条为收卷状态时,折叠链条整体上呈带状,当折叠链条为放卷状态时,折叠链条整体上呈管状。本发明采用的双卷筒的展开方式,能够有效的提高太阳翼工作面的收展比,通过折叠链条实现放卷状态支撑稳定、收卷状态顺畅可靠。
