The new TechRentals vehicle condition monitoring system enables detection of track problems while also allowing vehicle performance to be evaluated on a comparative basis. Developed specifically for railway applications, the new monitoring system offers potential for use in any analogous transport system.
Based on a GPS system updated at a 10Hz rate with measurements provided by a triaxial accelerometer, the vehicle condition monitoring system can be physically implemented easily, requiring the measurement apparatus to be placed in the vehicle for the duration of the journey.
The data is transferred to a memory card with the output in a unique format that utilises Google Earth data as reference to clearly show track abnormalities and also allows staff to compare the performance of different rail vehicles across the same section of track. The highly user-friendly format allows the concept and operation to be understood by the staff with minimal training.
The condition monitoring system offers the potential to investigate a relationship between vehicle design and adjustment, freight loads and speed with a view to maximising long term handling capacity from the existing track and increasing cost savings.
Key functions of TechRentals vehicle condition monitoring system:
- Allows extensive routine measurements to be taken without the use of specialised measurement vehicles at actual service speeds using standard vehicles
- No disturbance caused to normal track operation
- Allows savings by minimising track damage and establishing optimum vehicle speeds
- Also provides histograms summarising the horizontal and vertical vibration performance of the vehicle for different speeds
- Allows different vehicles to be compared across the same piece of track
