复合材料结构健康监测技术在飞机中的应用

摘要

结构健康监测(SHM)实现了工程结构设计与使用上的技术性跨越.将SHM应用于复合材料中,使得智能结构的设计与制造成为了现实.文章重点阐述了飞机复合材料结构SHM技术所面临的技术问题.SHM使飞机复合材料结构得视情维修以及降低其使用周期内成本成为可能,可以促使复合材料结构设计与制造的优化,最后指出了为实现复合材料SHMS所需要重点研究的理论与技术.%Structural health monitoring (SHM) achieves technological leaps in the design and operation of engineering structures. Composite materials incorporating SHM systems enable the design and manufacture of tailored smart structures. This paper mainly focuses on their application to aircraft as a means of highlighting the issues that face SHM in composite structures. Incorporation of SHM has the potential to reduce through-life costs by the adoption of condition based maintenance and to reduce operating costs by the design of more structurally efficient aircraft. The paper addresses issues involved in the design, certification, manufacture and through life support of such structures. Critical areas of development have been identified to enable the implementation of SHM in future composite aircraft structures.
