摘要/Abstract

摘要：

为了提高变体后缘的驱动效率,提出了一种可放大驱动力的索网传动机构。采用梁模型推导了单节点索网/基板弯曲变形的非线性微分方程,给出了基于有限差分法的迭代格式。数值模拟结果表明:索网机构比单索机构具有更高的驱动效率,降低了驱动器的最大驱动力;降低了基板的最大弯矩,且使最大弯矩点后移。最后,设计了单索和索网机构驱动钢板弯曲变形的实验装置,给出了钢板自由端垂直位移和外载关系的实验结果,结果表明当钢板等效偏转角的设计值为10°时,索网机构的最大驱动力比单索机构降低了41%。

Abstract:

In order to improve the driving efficiency of a morphing trailing-edge, a transmission mechanism with cable networks is developed to amplify the driving force. The nonlinear differential equation of a cable networks with a single node and mid-plate bending is derived. The iterative scheme is given based on the finite difference method. Numerical results show that the cable networks has a higher driving efficiency and reduces the maximum driving force compared with the single cable. In addition, the maximum bending moment of the mid-plane is reduced and the location of the maximum bending moment moves backward. Finally, an experimental device is designed and manufactured to test steel sheet bending with a single cable and cable networks. The experimental result of the relationship between the vertical displacement of the free end and the external load shows that the cable networks reduces the maximum driving force by 41% as compared with the single cable when the equivalent deflection angle of the steel plate is 10°.

Key words: morphing aircraft, morphing trailing-edge, transmission mechanism, soft transmission, cable networks transmission, force amplification
