| Abstract: |
| In order to analyze the tension performance of circular laminated rubber bearings under tensile loading,a tension model for analyzing the rubber layers is proposed based on the theory of elasticity in this paper.Applying the boundary restraint condition and the assumption of incompressibility of the rubber layer,the stress and deform expressions for the tensile rubber layer are derived.Based on the derived expressions,the stress distribution and deformed pattern especially for the deformed shapers of the free edges of the rubber layer are analyzed.The analytical results show that the stress and deform expressions can be used to simulate the stress distribution and deformed pattern of the rubber layer for circular laminated rubber bearings with different shape factors. |
