We design and build dynamometers and test rigs to industry standards or special requirements.  
RPTM dynamometers can include a variety of features . 

Dynamometer - Brake Drag (High speed, low torque)
  • Brakes-off DTV highway simulation 
  • Caliper drag
  • Fluid displacement

Dynamometer - Caliper Endurance (High torque, low speed)

Destructive testing

  • Torque Durability (Constant rotation)
  • Pressure pulse
  • Anchor bracket strength
  • Crack detection technology

Non-destructive testing

  • Anchor bracket deflection
  • Housing deflection
  • Correlation with customer FEA modelling

Dynamometer - Performance (High torque, high speed)

  • Burnishing & friction material performance
  • Driving cycle lining and rotor wear
  • Rotor quench testing
  • Brake thermal effectiveness & hysteresis

Test Rig - Caliper Benchmarking 

  • Pad & housing sliding friction
  • Guide pin boot pneumatic loads
  • Effects of lubrication
  • Piston retraction
  • Piston slide load
  • Piston knockback
  • Fluid displacement

 

RPTM can also design and build custom test equipment for a variety of applications. Please contact us with your application and requirements.
