Research & development support systems

Our unique mechanisms improve testing accuracy, which contributes to energy efficiency and accurate reproduction of phenomena.

Three-dimensional six-degree-of-freedom shaking table

Independent vibrations in the 2 horizontal directions, the vertical direction, and rotations around the 3 axes and their 6 degrees of freedom can be all combined as coupled vibrations, and sufficient data can be measured for destructive tests, which cannot be repeated.

Vibration control technology for destructive tests

  1. The reaction from the test specimen is measured, and reflected to the control in real time
  2. A real-time response filter is used to track the changes of characteristics in real time in vibration table including the test piece.

Deep underground development support system ( dynamic geotechnical centrifuge)

This is a vibration table for carrying out vibration tests for civil engineering, by rotating the arm to apply N times the gravity force to a 1/N scale model by centrifugal force. It is used for scale model testing of the ground.
