Abstract

In this study, the limitations of large strain resonant column and torsional shear tests apparatus are described and solutions to the limitations are also described. The limitations are rotational distance, limited torque, and measurable deformation system, respectively. To resolve the rotational distance, the bottom platen was modified. And the four-armed drive plate was modified into eight-armed drive plate and the drive coil connection was changed to obtain powerful torque.

본 연구에서는 대변형율 시험을 위한 공진주/비틂전단 시험기의 한계점과 해결방안을 기술하였다. 대변형율 시험의 세가지 한계점은 첫째, 시험기의 제한된 회전거리이며 둘째, 시험기의 제한된 비틂력과 셋째, 변형측정 시스템의 한계 등이 있다. 대변형율 시험의 제한요소 중에서 시험기의 제한된 회전거리를 해결하기 위하여 시료 받침대를 개량하였으며 비틂력을 향상 시키기 위하여 가진기 팔의 개수를 증가시키고 가진기 코일의 연결방법을 변경하여 보다 강한 비틂력을 얻을 수 있었다.
