Abstract
Optimal design of rib patterns is necessary to minimize the noise radiated from the shells of exhaust system components. Dynamic analyses of rib patterns were conducted using the finite element method and a closed-form solution. Five parameters were used to specify a rib pattern. The parametric study shows that the natural frequency is most sensitive to changes in rib height and orientation. A closed-form solution was developed to predict the dynamic characteristics of a rectangular plate with ribs.
