Abstract

The geotechnical centrifuge facility at Rensselaer Polytechnic Institute (RPI) has recently integrated a new control system with an existing 2-Directional (2D) in-flight shaker system. The purpose of the RPI 2D shaker is to provide a testing platform that is capable of providing dynamic shaking in two horizontal directions with minimal interference between the two directions. The system can reproduce any desired motion in one direction with precise control, while replicating a completely different motion in the other direction. This paper describes the 2D shaker mechanical design and its control system. For demonstration purposes, the calibration of three dynamic motions is discussed. The system has been fully tested and verified to accurately produce wide variety of dynamic and earthquake motions.
