摘要：

摘要：  针对仿昆扑翼微飞行器中压电驱动器的使用要求，采用复合材料的层合板理论和将能量法与实验法相结合的方法，推导了压电驱动器的静态位移、阻力、等效质量、刚度和阻尼系数的计算公式，得到压电驱动器的二阶集总参数模型.驱动器位移测试结果表明，利用推导公式计算所得位移的理论值比实测值小.同时，利用传递函数绘制的伯德图所得压电驱动器共振频率为2.540 kHz，与理论公式计算结果的误差仅为0.5%，从而验证了所建立计算模型的正确性.

Abstract:

Abstract： Flappingwing micro aerial vehicles demand high force, high displacement and low mass actuators. In this paper, the laminated plate theory, the energy method and experimental method were used to derive the displacement and block force, actuator’s equivalent mass, stiffness and damping coefficient. Then the second order lumped parameter model was obtained. The experimental results show that the actual displacement is larger than the theoretical value. According to the transfer function, the bode diagram   was mapped whose resonance frequency is 2.540 kHz. Compared with the theoretical value, the error is 0.5%, which proves that the model is valid.

Key words: flappingwing micro aerial vehicle, piezoelectric actuator, lumped parameter model
