摘　　要：精确控制副翼偏转角度对提高轻型飞机的操纵性能具有重要意义,将改进的空间四连杆机构——RSSR应用于轻型飞机副翼操纵系统的传动末端,采用方向余弦矩阵法建立RSSR机构运动的数学模型,并推导出该机构的位移方程,在ADAMS软件中对该机构进行参数化建模,确定目标函数、约束函数和驱动函数;优化算法选用广义简约梯度算法,对敏感程度较高的设计变量进行优化设计。结果表明:RSSR机构中各点的相对位置对副翼偏转角度影响较大,副翼上下偏转角度的相对误差分别从初始的2.35%与5%降低为0.100 5%与0.103 3%,采用RSSR机构可有效提高对飞机副翼偏转角度的控制精度。研究成果最终应用于某五座复合材料轻型飞机样机中。In order to make the angles of aircraft aileron deflection can be controlled more accurately, an improved spatial four-bar mechanism RSSR is applied to the end of the transmission mechanism of the light aircraft aileron control system. The mathematical model of the mechanism is established by the method of direction cosine matrix, and the displacement formula of the mechanism is derived. In order to make an optimization design of RSSR mechanism, the parametric model of the mechanism is established in the software of ADAMS, the objective function, the constraint function and the driving function are determined, the optimal design of the design variables with high sensitivity is carried out by the generalized reduced gradient algorithm. The results show that the aileron deflection angle has great influence by the relative position of each point of the RSSR mechanism, the relative error of the deflection angle of the aileron upward and downward are reduced from the initial 2.35% and 5% to 0. 100 5% and 0. 103 3% respectively, which demonstrated the optimization design for the mechanism meet the requirements of precision exactly. This research has been used in a prototype of a 5 seat composite material light aircraft finally.
