针对仿昆扑翼微飞行器对高效传动铰链的要求,从几何约束、应力条件、临界屈曲条件等方面,结合电磁驱动仿昆扑翼微飞行器对异质复合型柔性铰链进行了研究,给出了铰链的设计方法;研究了预应力对整个传动机构并联刚度以及铰链连接方式对整个传动机构串联刚度的影响;得到了传动机构中各铰链的宽度、厚度、长度、旋转刚度等设计参数.结果表明,整个传动机构的串联刚度是其并联刚度的135倍,满足了高效传递能量的要求;翅膀扑打角峰峰值达到了99.6°,较好符合了仿昆扑翼微飞行器的设计要求.
In order to meet the requirements of high imitation hunting flapping wing microengineer for efficient transmission hinges, the heterogeneous composite flexible hinges are studied from the aspect of geometric constraints, stress conditions and critical buckling conditions. The design method of the hinge was studied. The influence of the prestressing force on the parallelism of the entire transmission mechanism and the connection stiffness of the hinge to the series stiffness of the entire transmission mechanism was studied. The design parameters such as width, thickness, length and rotation stiffness of each hinge in the transmission mechanism were obtained. , The series stiffness of the entire transmission mechanism is 135 times of its parallel stiffness, which meets the requirement of high energy transfer efficiency. The peak of wing flapping reaches 99.6 °, which is in good agreement with the design requirements of imitation flapping wing micro-aircraft.
