Elastomer Design Validation using
Cosmos
FEA - Sales and Technical Support
from EGS India since 1997
|
Elastomers
such as rubber require special treatment due to material non-linear
behaviour. Cosmos FEA provides a rich set of resources for
accurately modelling real-world problems involving high geometric and
material non-linearities. Applications of Cosmos in non-linear
domain are wide ranging. Some of the functionalities include:
- Seal behaviour subjected to pre-stress due to
assembly and operational loading
- Inflation of tyres with steel/ nylon chord
reinforcements
- Assembly and operational strains in boots,
bellows, gaskets, door-seals, bushings, mounts and other visco-elastic
materials
- On-road condition simulation of wheel-tyre
assembly, for contact patch calculations and wheel radial fatigue life.
- Contact stress analysis of seals subjected to
pressure, temperature and frictional effects

Benefits of
Cosmos FEA for Elastomeric Product Design Validation
COSMOS FEA has been proven for design validation of many equipments
used in plastic product design. Some of them include:
- O-rings, Seals and Gaskets
- Tires - Air filled and Solid
- Bellows, ball joint boots and automotive
elastomers
COSMOS FEA can be used to determine:
- Strains ( assembly and pre-strain) and
Deflections in elastomeric components
- Efficiency of elastomeric joints for leak-proof
design and development
- Least Cost and Weight Designs
- Stiffness and deflections due assembly torque
- Creep and aging effects on elastomers
- Selective Optimization to reduce cost and weight
- Fatigue Life prediction and Failure Mode
estimation of load-bearing members and components
- Limit Load Analysis
