一种高精度航空结构多主体协作冲击定位方法

摘要

To improve the accuracy and real-time ability of the structural impact load positioning method, a precise impact positioning method based on aerospace structure multi-agent coordination is proposed for the advantages and disadvantages of the acoustic emission and the inverse analysis methods. In this method, two kinds of arithmetic work in parallel. They communicate information and interact with each other by the blackboard fusion to ensure the result accuracy while improving real-time ability. A large aerospace aluminum plate structure experiment shows that the impact positioning method is fast and efficient, with good robustness.%为了提高结构冲击载荷定位的精度和实时性,针对声发射和逆问题分析两类方法的优点和不足,结合多主体技术提出了一种高精度航空结构多主体协作冲击定位方法.两类冲击定位方法自主并行工作,通过黑板协作融合,彼此通信交互消息,参考优化定位结果,保证位置精度的同时提高了实时性.在大型航空铝板上的实验表明,该冲击载荷定位方法快速有效,具有很好的鲁棒性.
