Piezoelectric Ultrasonic Guided Wave Structure Health Monitoring SystemIntelligent Sensor and Detection Technology Research Center
Domestic instruments assist scientific research and engineering applications
-
Applicable objects
Fatigue cracks, corrosion, and connection status of metal structures, as well as impact damage and connection status of composite material structures
-
Basic principles
Using piezoelectric driving devices to excite guided waves into the structure, damage in the structure can cause changes in the propagation characteristics of guided waves (time domain, frequency domain, time-frequency domain features or patterns), and then obtain parameters and images related to structural damage through signal processing methods
-
Performance characteristics
Large detection range, high sensitivity, lightweight, and complex signal processing杂
-
efficiency
Compared to traditional point by point detection methods, piezoelectric ultrasonic guided wave technology has a longer propagation distance and smaller attenuation, enabling rapid non-destructive testing of large structural components with regular shapes. This not only reduces manpower and time investment, but also improves detection efficiency.
-
reduce costs
By combining wireless transmission technology and piezoelectric ultrasonic guided wave technology, the system reduces the cost of system construction and maintenance. At the same time, due to the improved detection efficiency and real-time performance, it also reduces production losses and maintenance costs caused by equipment failures.
