提出了一种基于推挽式双X压电驱动机构的后缘小翼型智能旋翼方案,开展了后缘小翼型智能旋翼模型的设计分析与试验研究。空载试验主要用于验证驱动机构的驱动特性,测试了压电堆和驱动机构的静态输出;为了验证悬停时小翼在铰链力矩作用下驱动机构能否有效驱动后缘小翼,进行了加载试验。试验采用线性霍尔传感器对推挽式双X型驱动机构在不同电压和频率驱动下小翼的偏转角度进行了测量。理论分析与试验测试结果基本吻合,压电驱动机构能够有效驱动后缘小翼,该智能旋翼方案是合理和可行的。
A kind of rear wing small wing intelligent rotor scheme based on push-pull dual-X piezoelectric actuator is proposed and the design, analysis and experimental research on the intelligent wing model with trailing edge small wing are carried out. The no-load test is mainly used to verify the driving characteristics of the driving mechanism and test the static output of the piezoelectric stack and the driving mechanism. In order to verify whether the driving mechanism drives the trailing edge winglets effectively under the hinge torque, Loading test. The test uses a linear Hall sensor to measure the deflection angle of the winglets driven by a push-pull double-X drive mechanism under different voltages and frequencies. The theoretical analysis and test results are in good agreement. The piezo-driven mechanism can effectively drive the trailing edge winglet. The intelligent rotor scheme is reasonable and feasible.
