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 CMM and provide a complete inspection report in less than 2.5 hours.
GOM’s TRITOP CMM 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 CMM 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 CMM 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.
