Brake Inertia Dynamometer

The Brake Inertia Dynamometer is arranged ‘in-line’, with the main elements being flywheel assemblies, brake test area, DC or AC machine, and a disc brake.

Construction of the Brake Inertia Dynamometer

  • A system of flywheels is mounted onto a common central shaft to simulate the mass of the test vehicle
  • The minimum inertia is formed by the inertia of the shafts, couplings, and disc brake
  • Variable inertia is obtained by engaging the appropriate flywheels
  • Precise inertia simulation is obtained by ‘trimming’ using the DC or AC machine
  • The flywheels are engaged manually with a unique support and transfer system or automatically, using electromagnetic clutches
  • A headstock is provided to mount the brake drum or disc
  • A tailstock is supplied to support the brake shoe or calliper assembly and to transmit the reaction torque to a high precision load cell
  • Speed is measured by an optical encoder and via a tachogenerator
  • The tailstock traverses on tee-slotted rails for alignment with the brake drum or calliper

Main Features:

  • Single or double work-heads
  • Variable inertia for vehicle mass simulation
  • Low friction driveline – minimum drag
  • High accuracy braking torque measurement and control
  • High accuracy deceleration measurement and control
  • High accuracy telemetric measuring equipment
