Critical to NVH, suspension rubber bushings can also be a source of noise due to dry friction. This thesis addresses the influence of dry friction at the bushing level. This work proposes a static FEM model of a simplified bushing geometry, recreating its prevalent deformation mode. It was built with Abaqus/CAE (DassaultSystèmes, France). The third-order Ogden’s model was chosen to reproduce the rubber's hyperelasticity. Its parameters were calibrated to load-displacement curves using optimization methods. The analysis revealed that radial deformation’s level and surfaces’ geometrical features directly impact friction sensitivity. This suggests a deformation range where friction might generate noise and shows the importance of part design.ABAQUSCAEHyperelasticitySuspensionFrictionRubber bushingStick and slipFinite element modelingToyotatext::thesis::master thesisthesis:33133
