Abstract

This paper documents a simple theoretical analysis and an experimental performance comparison of the advantages of an 8-post shaker rig relative to a conventional 7-post shaker rig. A simple static model describing the chassis roll and warp characteristics is first presented to illustrate the differences between 7-post and 8-post configurations, and the conditions where an additional aeroloader provides an advantage. Using a late model NASCAR Sprint Cup car, a series of experimental tests were conducted with the 8-post shaker rig at the Virginia Institute for Performance Engineering and Research (VIPER) facility in both 7-post and 8-post configurations. Experimental results confirm the hypothesis that an 8-post configuration is able to more accurately reproduce target motions of the chassis and suspension when those motions include a chassis warp condition.
