Every vehicle has a very specific geometric set that establishes the key kinematic and dynamic characteristics.
 GEO Systems “Discovery” 8 Post 26 Axis Electromechanical Test System The GEO system has 26 servo driven and controlled axis.
The tyre monitoring wheel pads have quick-change mounting to make hub mounting fast and uncomplicated.
The new system has also been developed on GEO to control typical error in overlap or shift between what is aero load verses what is wheel position. This is a great improvement over previous 3 post hydraulic loader systems. Fine resolution in attitude control is vital in accurately applying and shifting vehicle mass to distributed points.

IST eight-post racetrack rig at McLaren Racing sits at eye level, supported by an 80 tonne seismic base on isolation mounts.
Controlling downforce simulation is the critical factor and this is expressed as the RMS (root mean square) and the phase shift accuracy of the rig. In practice, IST produced a rig that was three times more accurate than the target figures. This was achieved by changes to the mechanics and hydraulics of the actuators, reductions in friction, improved compliant links (rubber bushes) between the actuators and the chassis and an advanced closed loop control technique. To illustrate the aerodynamic forces involved, typical Formula 1 racecar ground clearances of 40mm (front) and 80mm (rear) can be reduced to virtually zero at maximum speed (about 220mph).
Moog 8-poster system One of the services that VIPER (Virginia Institute for Performance Engineering and Research) which specializes in providing vehicle testing services to motorsports, automotive, and military customers, offers at the VIR RacePlex is “suspension tuning” using a Moog 8-post test rig.
The 8-post rig optimizes suspension setup primarily by maximizing the grip of the tires and by improving vehicle pitch behavior. |
