Module Development

Shaft-Ring Surface Contact Area O-ring Configuration

Axisymmetric models were created to replicate our Module designs to simulate frictional effects on the O-rings in our experiment.

Simulation Results (318 Insert) Piston Experiments

Factors O-ring Size (120,214,318) Pressure (250 psi-1750 psi) Squeeze (10%, 20%) Temperature (25 C, 150 C)

The The coefficient coefficient between between the the O-ring O-ring material material (viton) (viton) and and the the stainless stainless steel steel shaft shaft was was found found to to be be 0.25, 0.25, and and is is being being used used in in ABAQUS ABAQUS simulations. simulations.

Three different pressure simulations were conducted for each 0-ring size at 10% and 20% squeeze.
