Overview of the key technical issues in Chinese largest uniaxial centrifuge shaker

Centrifuge shaker is deemed as one of the most advanced and effective experiment equipment in geotechnical anti-earthquake field. In this paper, we pay close attention to three key technical issues encountered in the construction process of Chinese largest uniaxial centrifuge shaker, including the dynamic coupling characteristic between light-flexible base, hydraulic power element and soil model, and the influence of centrifuge vibration synthesis environment to three stage servovalve´s dynamic performance, as well as the servo control strategy aiming at better control performance. For these three issues, relevant research achievements of other scholars and our original efforts are briefly overviewed. Finally, the mechanical and hydraulic system, electronic control system, software system of the centrifuge shaker prototype is reported in detail.
