Real-time ultra-high-speed mobile (Shinkansen / Linear Shinkansen) deterioration / life diagnosis system

Real-time ultra-high-speed mobile (Shinkansen / Linear Shinkansen) deterioration / life diagnosis system

(RealTime, in situ, fsLaser Stereo Dynamic Shearography)

 

1. 1. Ends the conventional tapping sound inspection that relies on human wave tactics and manpower.

2. 3D Stereo Dynamic Shearography application using Laser.

3.2 RealTime non-destructive inspection of depth (depth) direction, scratches, cracks, defects, and cracks of ultra-high-speed moving objects (for example, trains, Shinkansen, linear Shinkansen, and other train vehicles) that move at 2880 km / h (800 m / sec). Destructive inspection.

4.2 From an inspection vehicle moving at 2880 km / h (800 m / sec), an inspection target within a length measurement distance of ~ 300 km can be inspected at 80 million points per second with a time resolution of 80 million points per second. The tapping sound is inspected with RealTime, and non-destructive inspection is performed with RealTime for scratches, cracks, defects, and cracks in the depth direction near the surface of the subject.

5. Proximity to measurement ~ 300km. Time resolution / measurement rate: 80 million points per second. Spatial resolution 6 μm. An ultra-high resolution tapping sound inspection system that applies a three-dimensional femtosecond laser.

6. Deterioration diagnosis and life prediction in situ while driving mechanical parts, concrete, metal, rails, and trolleys based on non-destructive, non-contact, non-invasive 3D tapping sound maps.

7. Non-destructive inspection of tunnel walls, etc. in situ and in real time from a running inspection vehicle.

8. Non-destructive inspection of rails in situ and in real time while driving from Doctor Yellow while driving.

9. Non-destructive inspection of bogies and rails in situ and in real time while traveling from train vehicles such as the running Shinkansen and linear Shinkansen.

10. Deterioration diagnosis and destruction of cracks, damage, breakage, and breakage due to erosion of the turbine blades (fan blades) and fan blades (fan blades) of engines during high-speed rotation of passenger aircraft, aircraft, and airplanes using Real Time / in situ. Prediction / life prediction.
