In this study, a long, thin and flexible carbon fiber reinforced composite cover was designed using the CAD module of Unigraphics NX program. Analysis results for different modes were obtained by applying modal analysis to this design with finite element method in ANSYS environment. The modal analysis process is explained in detail, and basic methods and mathematical equations are mentioned. Analysis results were examined in detail, and bending and torsion conditions were evaluated. Based on the analysis results, in order to improve the stiffness of the composite cover, a rib design was made and added to the initial design. A modal analysis process was carried out for ribbed cover design. As a result of the modal analysis, natural frequency values in different mode parameters were obtained and evaluated. With the addition of ribs to the initial valve design, an improvement of %35.52, % 38.79,% 58.07,% 129.11,% 100.35 and % 106.65 was observed in mode 1, mode 2, mode 3, mode 4, mode 5 and mode 6 values, respectively.
