During its lifetime, an aircraft structure is subjected to various impacts from various sources such as tool drops, hail, ground service equipment, etc. In modern composite structures, these impacts have a significant chance of generating barely visible damage (BVID) which may lead to catastrophic failure of a structure if left undetected to grow. However, BVID is difficult to detect during routine visual inspection without specialised non-destructive inspection and thus there is large interest in developing monitoring systems for estimating the location and severity of impact events. Currently, most systems and methods have been developed for controlled lab conditions and do not consider the wide range of impact parameters in real life operation (environmental conditions, vibration, impactor stiffness, angle, etc) which may severely compromise the accuracy of these methods. In this study we have explored two methods for maximum impact force estimation, deconvolution and a novel...

模拟环境和运行条件下复合板冲击力估算的新方法

在其生命周期中，飞机结构会受到来自各种来源的各种冲击，例如工具跌落，冰雹，地面服务设备等。在现代复合结构中，这些冲击很可能产生几乎看不见的损坏（BVID），这可能会导致如果未被发现会增长，则会导致结构的灾难性破坏。但是，如果没有专门的非破坏性检查，在常规目视检查期间很难检测到BVID，因此，人们对开发用于估计冲击事件的位置和严重性的监控系统非常感兴趣。目前，大多数系统和方法都是针对受控实验室条件开发的，并未考虑现实生活中的各种冲击参数（环境条件，振动，冲击器刚度，角度，等）可能会严重损害这些方法的准确性。在这项研究中，我们探索了两种估计最大冲击力的方法，反卷积和一种新颖的方法。
