Abstract
The present invention relates to a modular 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, long-stroke servo actuators are horizontally and vertically hinged in the modular shaking table; and an integration foundation is fixedly arranged on the upper end face of the shaking table body; an excitation platform is arranged in a short-stroke groove that is formed in the integration foundation, short-stroke servo actuators are horizontally and vertically hinged in the modular shaking table. The present invention is aimed at providing a large-scale and heavy-load modular shaking table that can meet the test requirements of realizing long stroke and high-frequency loading.
