Beam Centrifuge

The beam centrifuge makes it possible to achieve the same stress condition of actual structures can be applied in a prototype by applying a centrifugal acceleration of N times of earth gravity (1 G), to a 1/N scaled model of the ground. Introduction of the beam centrifuge at the Naruo Research Center in 1984 was a world’s first by a private-sector company. Since that time, centrifugal model tests have been carried out to study a wide variety of technical issues required in the construction of civil structures such as large-scale marine reclamation, shield tunnels, and the development of aseismic construction methods, etc. Thanks to the accumulation of research on processes that are necessary for cutting-edge experiments, namely, advanced development and design of model ground preparation and loading devices, Toyo can respond flexibly to diverse needs.
