摘要
阐述了多自由度大型地震模拟振动台由于试件重心高，偏心以及几何等原因在一个轴线方向上振动时，造成对其他轴线方向运动的干扰，同时介绍了克服这些干扰的控制原理。
Coupling vibrations of large scale specimen in earthquake simulation shaking table tests due to height, eccentricity of the specimen and geometry of motion of shaking table are explained and the principles for elimination of the coupling vibrations are introduced.
