Free Vibration Analysis of Circular Cylindrical Shells with Longitudinal, Interior Rectangular Plate
내부에 길이방향 사각판이 부착된 원통셸의 자유진동 해석
Abstract
The analysis of the free vibrations of a circular cylindrical shell with a logitudinal, interior rectangular plate is performed. The natural frequencies and the mode shapes of the combined shells are experimentally obtained by impact testing using an impact hammer and an accelerometer. The effects of the position of the plate on the frequencies and mode shapes of the combined system are examined. The experimental results are compared with a finite element analysis and show good agreement.
