CR200 탄소섬유 복합소재 프레임의 고유진동 해석

Abstract

This paper describes modal analysis for the body frame of 200 meter class multi-legged subsea robot, Crabster200(CR200). The body frame of CR200 is designed as a rib cage in order to disperse applied external loads and is made of carbon fiber reinforced plastic(CFRP) Therefore, the frame is lighter and stronger than a frame of the other conventional materials. In order to perform the reasonable FEA for CFRP body frame, we carried out specimen test of CFRP. Using the obtained material properties from the test, we performed modal analysis with respect to certain load conditions. fiber reinforced plastic(CFRP) Therefore, the frame is lighter and stronger than a frame of the other conventional materials.
