4Poster for squeak & rattle analisys

The Four Poster with triaxial input per wheel system is an enhancement of the basic Four Poster road simulator. It allows for every wheel pan the additional dynamic movement in the X and Y directions converting a four input system into a 12 input one.
The control electronics and computer system allow the reproduction of time histories.
When it is not needed the biaxial unit mounted on each wheel pan can be easily removed riconverting the system into the basic Four Poster.

The weight of each biaxial unit is about 20 Kg, the displacement + / - 20 mm in each direction and the maximum frequency about 50 Hz.
