在本文中，我们提出了一种新的基于吸引子的结构损伤检测技术，利用混沌激励。利用振动响应数据重构吸引子，吸引子对系统动力学的变化敏感。通过比较健康结构和损伤结构吸引子的变化，检测和定位损伤。我们用递归分析来分析吸引子的变化。数值算例验证了该方法的鲁棒性和灵敏度。
In this paper, we propose a new attractor-based structural damage detection technique using chaotic excitation. Attractor is reconstructed using vibration response data and sensitive to the change of the system dynamics. By comparing the change of attractors from healthy and damaged structures, we detect and localize the damage. We use recurrence analysis to analyze the change of attractor. Numerical example demonstrates the robustness and sensitivity of the proposed method.
