Foundation Block for 4-Poster Test System

Usually a 4-Poster foundation block is designed with a walk way in the middle to have access to the cars underbody to visually look for fatigue or other failures occuring during the test. The seismic mass can either rest on air springs as shown or on a gravel bed without any vibration isolation.

In most 4-Poster applications the concrete block is covered with cast iron floor plates. X-Y positioning systems make it convenient to adjust for different track widths and wheel bases to accomodate a large variaty of different cars. A steel floor cover is often used to drive onto the test system.
