Train Building Body-in-White

Manufacturers of modern rail vehicles need to guarantee sustainable mobility over the entire lifetime of their railroad cars. Today's coaches combine attractive design with technical innovation, and deliver optimal operational performance coupled with maximum reliability, availability, maintainability, safety, environmental protection and cost-efficiency. GOM's portable metrology systems support production controls and inspection of repairs and maintenance performed on railroad car bodies. They analyze inspection criteria that include body-in-white leveling to ground and wheel set, wall perpendicularity, and dimensions and distortions for door and window openings. Typically, one person can inspect a rail coach with TRITOP and provide a complete inspection report in less than 2.5 hours.

GOM's TRITOP system handles:

  • Measurement of 3D coordinates
  • Verification against CAD
  • Measurement of dimensions and angles
  • Measurement of standard geometries and mounting elements (threads, cylinders, edges, etc.)
  • Inspection sections

The ATOS full-field 3D digitizer is the system of choice when verification of an entire carriage surface is required.

Quality Control on Train Wagon Bogies

Another typical application for GOM's TRITOP system is verification of welded bogies for coaches. These swivel trucks are used in many European trains and are assembled at different locations throughout Europe. Therefore, each swivel truck needs to be measured and delivered with a measuring protocol. Using the TRITOP system, one person can typically inspect a bogie and create a measuring report within forty minutes. An automatic evaluation routine aligns the measured data with the nominal data, calculates any deviations, and prepares and prints the final measuring report.
