摘要
通过建立可变形机翼主动变形的仿真模型,分析压电纤维复合材料(MFC)驱动下的扭转变形,同时以地面实验作验证,研究了MFC在受电压载荷驱动下,对缩比模型主动变形产生的影响。结果表明,热弹性比拟法对可变形机翼在MFC驱动下的主动变形分析,是可行有效的;MFC的驱动效率和其与模型固定端的距离有关;同时,电压的加载方式和速度可进行自主化选择。
The torsion deformation under drive of MFC is analyzed by establishing the simulation model of the active deformation of the deformable wing.The influence of MFC with voltage load on the active deformation of the shrinkage ratio model has been investigated by implementing ground test as the verification.The results show that the thermal-elastic analogy method is a feasible and effective method for analyzing the active deformation of deformable wing driven by MFC.The drive efficiency of MFC is related to the distance between the fixed end of the model and itself.At the same time,the loading mode and speed of voltage can be chosen autonomously.
