针对实际航空结构大而复杂,传感器数目种类多,损伤形式多样等特点,引用主体和移动主体技术到结构健康监测系统。以真实机翼盒段结构为研究对象,利用主体协作技术自动监测盒段上翼面中的冲击损伤、应变分布、上翼面与肋之间抽钉失效的3种常见损伤;利用先进的移动主体智能选择传输路径,自动丢弃无用传感数据,提高整个系统效率;利用主体的学习能力消除了环境等因素对判定结果的影响,并解决边界监测问题。
Since the practical aviation structures are big and complicated, and there are large amounts of sensors to monitor many kinds of damage that may appear multi-agent and mobile agent technology are adopted in the structural health monitoring system (SHM). This paper takes the real wing box structure as the experiment object, using the agent cooperation technology," the impact damage, the strain distribution on the upper wainscot, and the bolt loosing between the wainscot and the rib are monitored automatically. Using the advanced mobile agent technology,the transmission path is chosen intelligently, and the useless sensor data is discarded automatically to greatly improve the efficiency of the whole system. Using the learning ability of agent, the environment effect on the result is eliminated, and more problems of monitoring the boundaries are well solved.
