Abstract

The invention discloses a structural health monitoring system for an aircraft. The structural health monitoring system comprises a sensor network for providing sensor signals to each subsystem; a first subsystem for carrying out quantitative monitoring on multiple damage of a large-size aviation structure; a second subsystem for monitoring tiny cracks in a high-stress area of an aviation metal structure and monitoring the damage of delamination, debinding and fibre breakage and the like in the high-stress area of an aviation composite material structure; a third subsystem for carrying out positioning on external bumping of the aviation composite material structure and load reconstruction; a fourth subsystem for carrying out distributed real-time measurement on strain of a key area of the aviation structure and corresponding load reconstruction; a fifth subsystem for carrying out prediction on the service life and residual intensity of the aviation structure; and a sixth subsystem for controlling and coordinating the work of the other subsystems. The structural health monitoring system provided in the embodiment of the invention overcomes the defect that the function of a conventional aircraft structure health monitoring system is single.

Description

technical field [0001] The invention relates to the technical field of structural health monitoring, in particular to an aircraft structural health monitoring system. Background technique [0002] At present, research on structural health monitoring (SHM) for aeronautical structures has become increasingly important. SHM is developed from traditional non-destructive testing technology. This technology uses a network of sensing / actuating elements integrated in the structure to perform real-time online detection of the structural state, which can effectively improve the safety of aeronautical structures, reduce maintenance costs and extend the service period. [0003] SHM technology is included in many research programs of domestic and foreign civil aviation companies. The Boeing Company of the United States has carried out humidity monitoring research on Delta767, and explored the adoption of SHM new technology on the new aircraft B787, conducted special demonstration and re...
