Millbrook uses its state-of-the-art electric drive system to propel vehicles to test speeds between 4kmh and 90kmh. A range of ramps, from a 0.5m to a 1.15m, are used to simulate left-hand-drive and right-hand-drive vehicle rollover crash test scenarios. Millbrook manufactures ramps of various heights angles to suit specific customer requirements. The large test arena ensures that no secondary impact occurs following the primary test.

Types of full-scale rollover crash tests

  • FMVSS 208
  • Ditch fall over
  • Gravel/Soil trip
  • Kerb trip
  • Corkscrew

Each test allows Millbrook’s customers to develop sophisticated vehicle rollover sensing capability and occupant protection countermeasures, including those around occupant ejection, roof crush and side curtain airbag deployment. Millbrook has a selection of Anthropomorphic Test Devices (ATDs), or crash test dummies, which are calibrated in-house for each test, and can perform up to 3 tests per day.

Millbrook can record up to 450 analogue channels, including accelerometers, gyros, pressure transducers, load cells, current clamps and displacement.

Cameras can be fitted on-board the test vehicle and around the facility to capture rollover crash test footage. A mixture of “normal” speed cameras typically filming at 24fps and high-speed cameras filming up to 2,000fps at full HD are available.
