Embedded shaking table test device with heavy load capacity and extensible test frequency and area

An embedded shaking table test device with heavy load capacity and extensible test frequency and area, comprising:

• a shaking table body, wherein
• the shaking table body being arranged in a building foundation in which a long-stroke groove is formed;
• a plurality of long-stroke servo actuators being horizontally hinged between the periphery of the shaking table body and the sidewall of the long-stroke groove at an equal interval;
• a plurality of long-stroke servo actuators being vertically hinged between the bottom side of the shaking table body and the bottom of the long-stroke groove at an equal interval;
• 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 being horizontally hinged between the periphery of the excitation platform and the sidewall of the short-stroke groove at an equal interval;
• a plurality of short-stroke servo actuators being vertically hinged between the bottom side of the excitation platform and the bottom of the short-stroke groove at an equal interval;
• and
• both the short-stroke servo actuators and the long-stroke servo actuators being electrically connected to a motion controller.
