Running characteristics test laboratory

Article: Running characteristics test laboratory

Vehicle reaction and contact geometry, vehicle dynamics testing

With approximately 45 staff and four working areas, this department is the most efficient in Europe and worldwide for dynamic and vibratory problems arising from the interaction between vehicles and track.

We specialise in planning, executing, analysing and assessing driving and vibration tests carried out on rail vehicles.

The tests are carried out in static and dynamic tests as well as stationary in the laboratory.

Accredited test procedures

  • Our test laboratory in Minden is accredited by Deutsche Akkreditierungsstelle GmbH (DAkkS) in the area of drive mechanics for rail vehicles in accordance with DIN EN ISO/IEC 17025. See the appendix for the accreditation certificate.
  • DB Systemtechnik is QMS certified to the ISO 9001 standard.
