Rail Transport Industry

The brand history of nCode software began with use in the rail industry during the 1980’s. Rail transport companies such as RATP and Bombardier continue to derive benefits from the latest generation of nCode products.

With nCode, problems can be identified before failure occurs, preventing serious derailments and accidents. Upfront design of train structures and bogies can be optimized for fatigue performance, thus saving weight and reducing energy required and damage to tracks. Operational measurements of strain and acceleration are collected on both train structures and tracks to predict failure and also assess damage.

With nCode software, rail transport engineers can:

  • Understand fatigue of railway components like wheels, bogies, axles, etc.
  • Understand field loading – how often are bumps seen, how many starts/stops per hour or mile, etc.
  • Fatigue analysis of structural members
  • Ride quality analysis to understand the impact of ride and track harshness on the riders
  • Remote monitoring of tracks

Example: Using nCode for fatigue analysis of the structure of trains

RATP: Fatigue analysis of the structure of trains with GlyphWorks, MGCplus and SoMat eDAQ

In France, the RATP (Urban Public Transportation in Paris area, 6th largest company of Urban Transportation world wide) are using GlyphWorks to process data primarily coming from HBM MGCplus and SoMat eDAQ data acquisition systems.

RATP uses nCode GlyphWorks for:

  • Fatigue analysis of the structure of trains (body, bogie, axle) and of the equipment fitted onto railway vehicles, but also of the rails.
  • Various analysis like statistics and general time-based and frequency-based analyses on signals of strain, vibration, displacement, temperature, pressure... for problems involving complex mechanical behavior.

According to David Courteille, mechanical division manager at the RATP test and measurement laboratory, one main advantage of GlyphWorks is its ability to work with large file sizes, while being very fast to process. The ease of use and existing database of material fatigue properties are also important advantages.

The MGCplus is used on-board for interactive applications. Its advantages are its compatibility with a large number of sensors and its large number of input channels (over 100 channels on a 19 inch rack.)

For unattended monitoring over several days , the SoMat eDAQ enables the collection of representative loading data to study for instance the fatigue behavior of structural welds. The eDAQs triggering and on-board processing enable it to store only the required data over a long period of measuring.
