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

A modular 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;
• an integration foundation being fixedly arranged on the upper end face of the shaking table body;
• an excitation platform being arranged in a short-stroke groove that is formed in the integration foundation;
• 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.
