Chassis shaker rigs are much like a dyno for the entire vehicle. They are more advanced in that they can test any kind of input and measure the forces and effects across the entire vehicle. Located in Hendersonville NC the Ohlins USA Vehicle Dynamics Simulator allows anyone with any suspension setup, Ohlins or otherwise, to utilize the test rig.

Think about using up tires, engine time etc when considering cost vs track testing. Often, like with a dyno, you can determine issues like friction and binding that would be otherwise impossible to find on track days. Safe low wear testing in a climate controlled room makes deep winter or peak summer testing more viable.

A 4-post utilizes a hydraulic actuator under each tire with a load cell. This allows the chassis dynamics to be investigated in a controlled environment much like a dyno. The rig day rate is around $4k plus some initial setup time and our day rate.

A 7-post rig takes the 4-post and adds 3 actuators connected to the chassis directly to simulate inertia and aerodynamic forces. The day rate is around $7k plus setup time and our day rate. The 7-post requires preparation of the car to accept actuator mounting and typically requires more thorough homework prior and just leading up to the test. This is more advanced testing and can be a very bad day if unprepared. We suggest starting with a 4-post test and learning all there is to gain from this before moving to the 7-post at a later time.
