Abstract
The present invention relates to an embedded shaking table with heavy load capacity and extensible test frequency and area, comprising a shaking table body; the shaking table body is arranged in a building foundation in which a long-stroke groove is formed, a plurality of long-stroke servo actuators are horizontally and vertically hinged in the shaking table; a short-stroke groove being formed on the upper end of the shaking table body; an excitation platform being arranged in the short-stroke groove; a plurality of short-stroke servo actuators are horizontally and vertically hinged in the shaking table. The present invention is aimed at providing a large-scale and heavy-load embedded shaking table that can meet the test requirements of realizing long stroke and high-frequency loading.
