NDT Inspection of Steam Train Car Roof
The owner of an amusement park contacted UTComp with concerns about their train car ride showing visible damage.
They wanted to know if the damage affected the structural integrity of the train and if they had any remaining service life left.
Inspection and analysis of FRP asset buckling revealed that visible damage did not compromise the structural integrity.
The asset for this case study was an FRP roof of a steam train car used at an outdoor amusement park. The owners of the train car identified buckling and sagging along the length of the roof and selected UTComp to evaluate the extent of damage and the car’s suitability for service.
- A UTComp Engineer collected data using the UTComp UltraAnalytix® system
- An UltraAnalytix® file was created for the roof and more than 60 readings were taken across the full width and length of the car
- Additional readings were taken at the areas of concern
The collected data was then analyzed, and heat diagrams were produced for each reading to show thickness and the percentages of design stiffness (PDS) for each reading. The area of concern was shown in greater detail. The analysis showed that the PDS was greater than the critical PDS and the engineering review threshold. This meant that despite the visible buckling, the structural integrity of the train car had not been compromised. Furthermore, the UltraAnalytix® analysis provided the client with valuable insights into the remaining service life of the train car.
