复合材料结构在线损伤（脱层）检测和健康监测技术的需求和要求很高。将压电传感器和致动器集成到复合材料结构中的基于振动的模型相关方法为满足这些要求和需求提供了一个有前途的选择。这些方法利用有限元分析技术，连同实验结果，以检测损坏。它们通过比较受损和未受损结构之间的动态响应来定位和估计损伤事件。根据分析的动力响应参数，这些方法可分为模态分析法、频域法、时域法和阻抗域法。模型相关方法能够提供全局和局部损伤信息。它们具有成本效益，并且相对容易操作。然而，在这些方法能够在实践中实施之前，仍然存在许多挑战和障碍。
There are strong needs and requirements for on-line damage (delamination) detection and health-monitoring techniques on composite structures. Vibration-based model-dependent methods with piezoelectric sensor and actuator incorporated into composite structures offer a promising option to fulfil such requirements and needs. These methods utilize finite element analysis techniques, together with experimental results, to detect damage. They locate and estimate damage events by comparing dynamic responses between damaged and undamaged structures. According to the dynamic response parameters analyzed, these methods can be subdivided into modal analysis, frequency domain, time domain and impedance domain. Model-dependent methods are able to provide global and local damage information. They are cost-effective and are relatively easy to operate. However, there are still many challenges and obstacles before these methods can be implemented in practice.
