| 对飞行器结构中的裂纹、腐蚀、脱层、材料性能退化及其它损伤进行及时且准确的检测是确保服役飞行器安全可靠运行的必要手段。结构健康监测是确定结构完整性的革命性创新技术,它在飞行器的结构设计、飞行及维护过程中都可发挥重要作用,它的使用可以提高飞行安全性、降低维护成本。本文简要介绍结构健康监测的系统组成、基本原理及关键技术,并通过实例阐述了基于智能层的结构健康监测技术在飞行器上的应用情况。 |
| 英文摘要: |
| Timely and accurate detection the cracking, corrosion, delamination, material degradation and other types of damage in an air vehicle structure is essential to ensure the safety and reliability of in-service aircrafts. Structural health monitoring (SHM) technology is regarded as a revolutionary method for determining the structure integrity. It plays an important role in aircraft design, flight and maintenance. The application of SHM can improve flight safety, reduce maintenance costs. The system composition, basic principles and key technologies of SHM are introduced in this article. Through examples, the application of SHM technology for air vehicle based on SMART Layer is also elaborated in this article. |
