Acoustic Wave (Acoustic Emission)
Damage Monitoring of Structural Parts
1.1 Application Scenes:
Suitable for structural damage monitoring of various materials and equipment, such as bridges, wind turbines, cutting tools, storage tanks, pressure vessels, aerial work platforms, etc.
For example, cracks in metal and non-metallic structures such as bridges and dams, cracks in petrochemical tanks or pressure vessels, cracks in valves and pipelines, cracks in rotating equipment such as generators and lathes, etc.
1.2 Technical Principles:
The damage processes such as cracks, deformation and delamination in structural materials are often accompanied by sound waves (acoustic emission). The sound wave is acquired and analyzed, and the type, degree and location of damage can be determined by the acoustic wave (acoustic emission) system, and a health assessment can be made on the integrity of structural components.
