AMERICAN ENGINEERING GROUP
• Model: Highly nonlinear,transient FSI, strong coupling
• Boundary condition load:- Sinusoidal displacement - Amp= 0.05 mm
Example: Hydromount Study - 2d Axisymmetric model
Hydromounts used in automotives to damp vibrations caused by the engine mount
Rubber Wall: Mooney Rivilin(non-linearincompressible)
Fluid chamberHighly viscous oil

Example: Contact problem in rubber components
• Most rubber parts are involved in assemblies and contact with other
parts.

AMERICAN ENGINEERING GROUPDesign optimization example: Engine Mount
Area reduction: – 16.7%
OptimizationFEAAnalysis
Optimization Problem:
• Objective: minimize area of the mount• Constraints:
– maintain the stiffness as in theinitial design;
– keep the hydrostatic pressure atcritical points in an admissiblerange
Pro/E Model
