Design and Implementation of Shaking Table using Stepping Motor

스테핑 모터를 이용한 진동대의 설계 및 구현

This study is focused on the design and performance test of shaking table using stepping motor. Stepping motor can control the motion accurately with generated pulses and is applied to the shaking table. Earthquakes like El Centro and Taft are used as inputs to the shaking table. First, the number of pulses are calculated and sent to pulse generator. Then, the generator controls the table according to the pulse signs. It is shown that the measured signals from the table are in very good agreement with input signals of scale-downed earthquakes of El Centro and Taft. This table will be used for the experimental study of small-scaled building structures with tuned mass dampers under earthquakes.
