000018305 520__ $$2eng$$aMany considerations factor into the decision of what type of shake table to purchase: capacity, cost, operation, and fidelity. One aspect of fidelity that is seldom considered or understood is the dynamic cross-coupling that occurs between degrees-of-freedom (DOFs). A table with low cross-coupling has a natural tendency to move in the desired DOF without causing motion in the other DOFs. Cross-coupling is greatly influenced by actuator geometry. Most shake tables fall into one of five categories depending on their actuator configuration. In this paper, these five configurations are analyzed, compared, and ranked from a cross-coupling standpoint. Both for buyers of new shake tables and owners of existing tables, this analysis may promote a deeper understanding of fidelity limitations that arise due to actuator configuration.
