ABSTRACT

This chapter discusses the Finite Element Model (FEM) of a typical cylindrical thin-walled composite part or cylindrical part is established in ANSYS. By using the FEM, the vibration modes and buckling modes of the cylindrical part are calculated with the fiber angle 0°, 30°, 45°, 60° and 90° respectively. The angle between the carbon fiber and the axis of the cylindrical part is defined as the fiber angle. The thickness value of the shell element is the wall thickness of the cylindrical part. The method will also be used to analyze the cylindrical part. The boundary condition is to constrain all degrees of all nodes on the cylindrical part bottom surface. Finally, the first 10 order natural frequencies and modes of the cylindrical part are extracted from the simulation results. From the simulation results in the table, the 1st order buckling critical load of the cylindrical part is the highest when the fiber angle is 0 degrees.
