摘　　要：提出一种展向连续变弯度机翼设计方法,当电推杆直线运动12 mm时,机翼最大变形角度为45°。变弯度机翼的运动仿真结果证明机构的变形过程具有良好的平稳性与可控性。基于Workbench中的Static structure与Fluent模块,分析变弯度机翼的承载运动误差。结果表明:蒙皮变形载荷使机构运动产生反向的运动误差,电推杆线性位移为8.77 mm时,最大运动误差为6.67%,蒙皮厚度与运动误差呈正相关;气动载荷使机构产生正向运动误差,机构在气动载荷与蒙皮变形载荷共同作用下,最大角度误差不超过7%,表明展向连续变弯度机翼机构在给定工况下具有良好的变形承载能力。A spanwise continuous variable camber wing design method is proposed.When the electric pushrod moves 12 mm in a straight line,the maximum turning angle of the wing is 45°.The motion simulation results of the wing with variable camber demonstrate that the bending process of the mechanism has good stability and controllability.Based on the Static structure and Fluent module in the Workbench,the load-bearing motion error analysis of the deformed wing with variable camber is carried out.The analysis results show that the deformation load of the skin causes the reverse motion error of the mechanism.When the linear displacement of the electric pushrod is 8.77 mm,the maximum motion error is 6.67%,and the skin thickness is positively correlated with the motion error;The aerodynamic load causes the forward motion error of the mechanism.The maximum angle error of the mechanism under the combined action of aerodynamic load and skin deformation load is not more than 7%.The results show that the continuous variable camber wing mechanism designed in this paper has good deformation bearing capacity.
