| 摘要: |
| 为满足柔性后缘结构空间的限制条件,设计一种用于驱动柔性后缘变形的单索传动机构. 建立基板和单索耦合的非线性微分方程,给出了求解方法和具体算例．分析结果表明: 所设计的单索传动机构可以实现后缘结构在0°和20°偏角范围内的任意变形,偏转角和驱动力之间以及偏转角和索位移之间均具有较好的线性关系; 索施加在各个限位滑轮上的压力随着后缘偏转角的增加而增大,作用在限位滑轮的最大压力仅为输入力的20％左右．所研究的成果可为柔性后缘的驱动结构设计提供一定的理论依据． |

| Abstract: |
| To satisfy the constrain of structure space of flexible trailing edge, the single cable transmission mechanism is designed in this paper. The nonlinear differential equations coupled by the mid-plate and single cable are derived, and the solving approach and the calculational example are given. The results show that the single cable can be actuated any deformation of the flexible trailing edge within the deflection angle between 0° and 20°. The linear relationship between the deflection angle and the driving force is good. So is the deflection angle and the displacement of cable. The pressure load on every limit pulley increases as the deflection angle increases. The maximum pressure load exerted on the limit pulley is about 20％ of the input force. |
