基于波动的结构健康监测是土木和机械结构损伤检测的一个新兴研究领域。为了将SHM应用于多线电缆,本文对超声波在这种耦合波导中的传播进行了理论、数值和实验研究。除了瞬态有限元模拟之外,还提出了新型的基于能量的模型。利用这些模型,可以执行具有许多电线的电缆的有效模拟。有限元模型和能量模型都通过复杂的实验进行了验证。
Wave-based Structural Health Monitoring (SHM) to detect damages in civil and mechanical structures is a growing research field. In order to apply SHM to multi-wire cables, in this work, ultrasonic wave propagation in such coupled waveguides is studied theoretically, numerically and experimentally. In addition to transient finite element simulations, novel energy-based models are presented. With these models, efficient simulations of cables with many wires can be performed. Both finite element and energy-based models are verified with sophisticated experiments.
