Vehicle Development

Millbrook’s experienced engineers and project managers work with customers globally on a wide range of programmes.

Millbrook provides subjective and objective measurement, robustness and durability tests and supports the design and development of vehicles. It has ISO17025 accreditation for certain environmental tests.

The teams of engineers are backed up by a wide range of testing facilities in the UK and Finland, including component test laboratories, environmental chambers, noise measurement sites and over 2,200 acres of proving grounds with specialist tracks, surfaces and indoor and outdoor facilities replicating almost all driving conditions for real-time and accelerated life cycle tests.

System and Component Testing

A wide range of system and component testing solutions.

Offering independent product test and validation, Millbrook can subject test pieces to single and multi-axis vibration, temperature, humidity, saline solutions, dust and solar exposure – in a range of combinations, accurately and repeatedly.

The flexible engineering teams have wide-ranging experience of customer procedures and legislative tests in structural and durability testing including fatigue, cyclic and quasi-static load tests using electric, pneumatic or hydraulic actuators. Their strength is the ability to develop procedures for bespoke test solutions to meet customers’ specific product validation needs.
