摘　　要： 卷尺弹簧是形状类似钢卷尺的一种构件,拥有单层开口柱面壳的结构形式.可以利用其壳体屈曲性能,设计和研制出一种铰链结构.这种铰链结构具有独特的力学性能,它可以利用折叠时积聚的弹性应变能实现结构的自动展开而不需要其它的动力装置;在展开之后,又能够靠自身的刚度提供大型可展结构所需的锁定力,而不需要另外加设锁定装置.这种铰链在大型航天可展结构(如可展的太阳翼)中具有一定的应用前景.纯弯屈服是其应用之前必须解决的问题. A tape spring with a shape of steel spring has a configuration of ringent cylinder shell. It has special buckling properties. A new type of hinge using this special buckling properties can be designed. This new kind of hinge has unique mechanics and it is both self-powered and self-latching. So there is no need of additional power and lock equipment. This kind of new hinge can be used in large deployable structures such as solar arrays. Before the application of the hinge, the problem of the yielding must be resolved. And the thoery of the unfolding is the basis of the APP of the tape spring.
