采用有限元分析软件ABAQUS对单簧片的折叠过程进行了数值模拟分析，研究了单簧片正反向折叠过程中临界弯矩、稳态弯矩、最大应变能的变化规律，并利用临界弯矩、稳态弯矩、最大应变能等参数作为簧片驱动能力和抗干扰能力的参数指标，研究了截面圆心角和长度对单簧片驱动能力和抗干扰能力的影响。结果表明：随着截面圆心角的增加，簧片驱动能力和抗干扰能力都呈现增强趋势，随簧片长度的增加，其驱动能力和抗干扰能力会有所下降。该研究对于提高空间展开结构的运动精度以及可靠性具有一定的参考价值。

The bending process of the single tape spring was simulated based on ABAQUS software. The variations of critical moment, unfolding moment, and maximum strain energy in the bending process were investigated, and the effects of different radius angles of section and length on driving capability of the simple tape spring was studied by using these parameters. Results show that the driving capability and resisting disturbance capacity grow with the increase of radius angle of section in the bending process of the single tape spring. On the other hand, these capabilities decrease with increasing length of the single tape spring. The research has a certain reference value for improving the kinematic accuracy and reliability of deployable structures.
