Abstract

Thermally induced vibration response of composite thin-walled beams is investigated in this paper. The flexible spacecraft appendages modeled as thin-walled beam incorporates a number of nonclassical effects of transverse shear, primary and secondary warping, rotary inertia and anisotropy of constitute materials. Thermally induced vibration responds characteristics of a composite thin walled beam exhibiting the circumferantially uniform system(CUS) configuration are exploited in connection with the structural flapwise bending lagwise bending coupling resulting from directioal properties of fiber reinforced composite materials and ply stacking sequence. A coupled thermal structure gradient is investigated.

본 논문에서는 복합재료 얇은 벽보의 열진동 응답에 대해 연구하였다. 복합재료 얇은 벽보로 모델링한 위성체 유연 구조물은 회전관성과 1차, 2차 와핑. 전단변형의 비고전적 요소를 포함한다. CUS구조물로 모델링한 복합재료 얇은 벽보의 열진동 특성은 적층순서와 섬유강화복합재료의 방향특성인자로부터 기인된 종방향 굽힘과 횡방향 굽힘이 연성과 관련하여 연구되었다. 열에 의한 구조물의 변형과 온도 구배가 연성된 열 진동에 대한 해석이 수행되었다.
