This part of the DTL portfolio belongs to the traditional ones. Wheels and axles are an essential component of every type of rail and road vehicle and they are in the centre of our attention. Our technological knowledge and long-term experience guarantee quality to our customers and demonstrate our competence.

What is tested

• Railway wheels according to ČSN EN 13262
• Railway axles according to ČSN 13261, ČSN EN 13260 a ČSN EN 13 103-1
• Measurement of residual stress of the axle

Test bench basic parameters

• Rotation derived by an electric motor controlled by a frequency converter
• 16-channel surface stress measuring system
• Clamping round plate for wheels and wheel substitutes up to 1,500 mm in diameter

Options and advantages

• Load frequency up to 25 Hz depending on the selected imbalance
• Computer-controlled operating program with automatic diagnostics and data aquisition
• Circularity check of the loading
• Round clamping plate mounted on a sprung block
• Automatic detection of a fatigue crack or degradation of a pressed joint

Measurement of residual stress of the axle

• Semi-destructive mechanical relaxation method according to ČSN EN 13261 clause 4.6 and evaluation according to ASTM E837-20
• Internal stress measurement performed using the RS-200 drilling equipment
