Due to increasing operating speeds of rail vehicles, the aerodynamics and its impact to the immediate environment plays an ever more important role. Another expansion of our scope of accreditation is the field of aerodynamics. PJM carries out measurements for the verification of compliance with statutory limits according to TSI and TSI HS and furthermore according to the standard series EN 14067.

Test method

• Pressure changes in an undisturbed pressure field (reference case)
  • Measurement of the peak-to-peak pressure signal on open track

• Flow effects on people next to the track (reference case)
  • Measurement of flow velocities (2D)

• Pressure changes on surfaces parallel to the track
  • Measurement of absolute pressure using a pressure measuring plate

• Maximum pressure fluctuations in tunnels
  • Measurement of absolute pressure and flow velocity
  • Simulation to determine the reference case using measured data
