The 7 post shaker is a piece of test equipment used to perform technical analysis on racecars. A 7 post shaker can apply all vertical forces acting on the car on the racetrack, emulating some of the effects of driving. The shaker has many controls for the hydraulic system and sensors to measure forces and their effects on the car. The forces include banking loads, lateral load transfer, longitudinal weight transfer and ride height sensitive downforce.
