Life Assessment of Valve Component Subjected to Internal Pressure Loading

Business Needs

• Estimate stress concentration and resulting deformation for critical regions.
• Evaluate structural strength of the valve assembly at given temperature.
• Safety operations and avoiding cost overruns by manufacturing faulty designs.

Challenges.

• Applying exact boundary conditions to replicate real world conditions on the model.
• Developing an accurate CAD geometry for precise end results.

HitechDigital’s Solution.

HitechDigital engineering teams developed CAD model for the gate valve assembly from which an FE model was created to perform simulations. By replicating real world conditions the results were generated which showed that the designs were accurate for valve assembly to function within safe stress limits.

Approach.

• HitechDigital experts generated CAD geometry for the valve assembly through which FE model was generated for simulation by applying appropriate boundary conditions to match real world simulations.
• The structural analysis performed on the valve assembly as well as individual components, provided useful insights on stress generation and deformation values. A detailed evaluation was done to map out stress concentration on concerned areas of the valve assembly, and the design was found to be within the safe stress limits.

Benefit.

• Measurable reduction in conducting physical tests trials which significantly reduced the cost involved.
• Future design modification was made possible to accommodate fluids at different temperatures.

Client Speaks.

With a prior analysis results and design validation reports prepared by HitechDigital FEA specialists and experts, we could save umpteen resources. We would recommend HitechDigital to anyone.

Result.

• Accurate CAD model provided 40% reduction in time required to develop the prototype.
• Sharp decrement in costs and design development time was noticed which accelerated manufacturing.
