The design development of rubber metal bonded parts components is an art as well as a science because of the peculiar non-linear relationship the properties of rubber material are fused with the geometry of the component to provide the right stiffness, damping and life of the components under service conditions.
Rubber materials undergo large deformations and strains when used under demanding conditions in automotive, biomedical and aerospace applications. The characteristics of these materials to undergo large deformations without permanent plastic stress accumulation along with high energy absorption capability makes them ideal materials for engine mounts, vibration isolators, tires and under the hood components like seals, gaskets, o-rings etc.
AdvanSES has the capability to fully characterize the hyperelastic rubber materials, generate the moon-rivlin, ogden, yeoh etc., material constants and carry out the finite element analysis FEA using Abaqus to generate a fully capable, prototype design. We can provide the following tasks depending upon the OEM scope of the component.
- Generate the design with the prescribed stiffness in X, Y and Z directions.
- Remove hot spots and provide an optimized design with stress-strain distribution.
- Provide feedback on the rubber elastomer compounds.
- Test for damping properties at the material and component level.
- Generate and provide test results for critical tearing energy and intrinsic strength of the rubber materials.
- Correlate the intrinsic strength property with FEA design stresses to optimize the fatigue life of the components.
