| Abstract: | The Nonlinear Finite Element Analysis was applied to study the stress and modal of an air spring, which is composed of composites with multiple orthotropic materials. Composites and nonlinear geometry of large deformations were considered during numerical analysis. By selecting the thickness of each ply, better stress distribution on the air spring has been obtained. And the preceding six mode shapes are calculated through modal analysis. |
