TESTING SYSTEM WITH SOFT REACTION STRUCTURE

摘要

A testing system (10) includes a soft reaction structure (30) formed by column assemblies (26), a base (22) and a crosshead (30). Compliant devices (44,44') are disposed between the column assemblies (26) and the base (22) and/or the crosshead (30) to isolate interaction of these components and reduce structural vibration mode excitation.
