Abstract
본 논문에서는 균일 열부가 하중을 받는 사각판의 자유 진동특성을 중첩법에 의한 수치해석과 유한요소 해석을 통하여 연구하였다. 사각판의 재질은 알루미늄, 강재 및 스테인레스강 이다. 부가한 온도 조건은 상온에서부터 <TEX>$300^{\circ}C$</TEX>까지 부가하였고, 경계조건은 자유-자유 조건이다. 완전 대칭 모드, 완전 역대칭 모드 및 대칭-역대칭 모드에 대한 해석이 수행되었다. This paper was conducted on analytical solution using superposition and FEM analysis in the free vibration analysis of rectangular plates under uniform thermal loadings. Materials of three rectangular plates were aluminum, steel and stainless-steel respectively. Applied temperature conditions were from room temperature to <TEX>$300^{\circ}C$</TEX> and boundary condition was free-free condition. Fully symmetric mode(FSM), fully antisymmetric mode(FASM) and symmetric-antisymmetric mode(SAM) were analyzed.
