Tracking Study on International Large Scale Centrifugal Shakers of 40g-t and Key Technology
Centrifugal shakers are widely regarded as state-of-the-art testing facilities of geotechnical earthquake engineering for providing an effective solution for the unequal gravity stress between models and prototypes typically in traditional test methods. Currently only two large centrifugal shakers are in the United States and Japan respectively, whereas no one has been established in China. Such situation remarkably lags behind the serious seismic conditions and the world largest construction scale of civil engineering in China. Due to the lack of experiences and the lot of difficulty, one significant task of large scale centrifugal shaker construction is tracking study on the world advanced facilities. The paper outlines the technology parameters and components of the two existing large centrifugal shakers. Through investigating and comparing the structural characteristics of the two facilities, the differences between the two are summed up and analyzed. The analyses indicate that key technologies mainly centre upon centrifuge arms, centrifuge buckets, exciting devices, power sources and guide-support devices. The results can provide assistance and reference to the construction of foreign and domestic large scale centrifugal shakers.
