摘　　要：将压电陶瓷驱动器和柔性铰链四杆放大机构融为一体,设计了结构紧凑的微扑翼驱动装置,并采用粒子群算法完成了微扑翼驱动装置结构参数优化设计;采用拉格朗日方程来建立微扑翼驱动系统动力学模型,对动力学性能进行了仿真研究.研究结果表明:采用正弦驱动电压,微扑翼驱动装置可以实现稳定扑打运动,另外,采用标准正弦驱动电压,在某一频段微扑翼驱动装置能实现高效扑动,而且通过调整驱动电压幅度能够控制扑动幅度.该研究为微扑翼飞行器运动控制奠定了基础.By combining piezoelectric ceramics actuator with flexible joint four-bar mechanism,the paper designed a compact driving equipment for micro flapping flight,and optimized its structural parameters by means of the particle swarm optimization.Using the Lagrange equation,the paper also gave a dynamic model of the driving equipment,and investigated its dynamic characteristics through simulation.The investigation result shows that,with sine wave driving voltage,the driving equipment of micro flapping flight will...
