Powertrain Vibration Testing

At a glance

Millbrook tests complete vehicles and laid-out powertrains for vibration and performance in a laboratory environment using 4WD Powertrain Rigs located in the UK and the USA.

The vehicle is mounted on four independent hub dynamometers and fully instrumented.

A significant advantage of laboratory testing is that sensors, sensor-cooling and logging equipment can be installed where it would be impractical or impossible to do so for road testing.

Also, drive cycles can be generated in the laboratory from real-life road data and performed in a consistently controlled manner, providing significantly more repeatable data. Millbrook replicates both steady state and transient conditions.

This type of testing can be used to measure driveline and exhaust system vibrations and investigate interactions between the vehicle body, engine, transmission and mounting brackets. It provides results that are not possible to obtain through purely component-level testing.
