Abstract

The UAV cluster combat puts forward higher requirements for short-distance arresting gears for multitype aircraft. Based on magnetorheological technology, an arresting gear was designed, and the structural parameters of the MR damper were optimized. An iterative optimization method of structural parameters via a genetic algorithm combined with parametric modeling and magnetic field simulation was proposed. The optimization method was applied to optimize the structure of both a single-coil and double-coil damper. The performance of the optimized arresting gear was studied. The results show that, under the same zero field damping upper limit, the variation range of the damping force of the double coil increases by 10.2% compared with that of the single coil. Comparing the peak overload of UAV before and after the optimization, when the UAV mass increases from 4000 kg to 10,000 kg, the reduction in the peak acceleration is increased from 19.8% to 25.4%. Compared with traditional hydraulic arresting gear, the new arresting gear has good adaptability to UAVs with various qualities and has higher arresting efficiency. This arresting gear has a certain advanced nature.

基于磁流变阻尼器的制动齿轮设计与结构优化

无人机集群作战对多型飞机的短距离拦阻齿轮提出了更高的要求。基于磁流变技术，设计了阻止齿轮，并对磁流变阻尼器的结构参数进行了优化。提出了一种基于遗传算法、参数化建模和磁场仿真相结合的结构参数迭代优化方法。将该优化方法应用于单线圈和双线圈阻尼器的结构优化。对优化后的拦阻齿轮的性能进行了研究。结果表明:在相同的零场阻尼上限下，双线圈阻尼力的变化幅度比单线圈增大了10.2%;对比优化前后无人机的峰值过载，当无人机质量从4000 kg增加到10000 kg时，峰值加速度降幅从19.8%提高到25.4%。与传统的液压拦阻装置相比，新型拦阻装置对各种品质的无人机具有良好的适应性，具有更高的拦阻效率。这种拦阻装置具有一定的先进性。
