Workshop 6
Nonlinear Contact Analysis of a Control Valve including Gasket Behavior

 This control valve has two gaskets, and the objective of the analysis is to optimize the gasket design. Workbench does not yet have gasket elements, so students use DRD developed commands objects to add gasket elements to the model. The model also involves bolt pretension, pressure, mechanism forces, and thermal loads. The model requires linear and nonlinear contact types. Students define temperature dependent material properties.

The initial design does not have a viable gasket design, and students use a design parameter and DesignModeler to modify the design to achieve an optimum gasket design.
