Four poster rig

Four-Poster Rig

A hydraulically powered road simulator capable of motion up to frequencies of 30Hz, whereby road roughness is represented by the independent vertical motion of four actuators.

It is used for projects on vehicle ride dynamics and is also reconfigurable, to allow component tests.

The rig also houses a 'quarter car' structure, also driven by a single actuator, to demonstrate vehicle ride dynamics and for student studies on automatic (semi-active) ride control.
