基于声子晶体理论的无人机自动驾驶仪减振方法

Vibration Method of UAV Autopilot Based on Phononic Crystal Theory

将声子晶体理论引入无人机自动驾驶仪的减振设计。在此基础上,设计了局域共振减振板,并采用遗传算法对局域共振减振板的材料力学参数和结构参数进行了优化设计。仿真和实验测试结果表明,局域共振减振板对无人机自动驾驶仪具有较好的减振功能。

The theory of phonon crystal was introduced into the design of vibration absorber for UAV autopilot. The local resonance vibration damper plate was design, and its structure and material parameters were optimized with genetic algo- rithm. The results of simulation and experiment showed that the local resonance damping plate had good vibration reduc- tion function for the UAV autopilot.
