Abstract
Minimizing the strain energy in an oring
seal has been identified as a mode of improving its
useful lifetime. The intent of this research was to manipulate the strain energy content in oring
seals by varying material properties and material behavior over the crosssection
of the oring.
Oring
designs were developed that contained regions of modified material properties referred
to as insets. These oring
designs incorporating insets were evaluated numerically to
determine the effects that the inset’s stiffness, size, and placement, had on the strain energy
content and maximum sealing pressure of the oring
design. Achievements included the
development of oring
designs that demonstrated lower strain energy content than a baseline
design made of a single homogeneous material.
Experimental orings
were created using commercially available materials. Compression set
and compression stress relaxation experiments were conducted. Performance of new oring
designs including insets made of a softer material than the main oring
was compared to
baseline single material orings.
Improved sealing performance was demonstrated by a
decreased rate of sealing force decay over time, and by decreased compression set, for the new
oring
designs proposed.
