Pressure Hull FEA and Optimization (Ansys)

Job ID: 40441913

Budget: ₹600 – ₹1,500 INR

Project Title:
​Static FEA Optimization of Ring-Stiffened Pressure Hull (Ansys)

​Project Description:
​I am seeking an FEA specialist to perform a comparative structural analysis on a cylindrical pressure hull. The objective is to identify the most efficient scantling arrangement by analyzing the relationship between frame spacing, weight, and Von Mises stress.

​1. Structural Parameters
​Geometry: Cylindrical shell with hemispherical (dome) ends.
​Diameter: 6.2 m.
​Total Length: 67 m.
​Stiffeners: Internal ring frames (T-sections).
​Loading: Uniform external hydrostatic pressure (specific depth value will be provided).

​2. Scope of Work
​Modeling: Build a parametric model in Ansys that allows for rapid iteration of ring frame spacing and thickness.
​Analysis: Perform Linear Static Structural Analysis for multiple configurations.
​Comparative Study: Evaluate how changing the frame spacing affects the structural integrity versus the total weight of the hull.

​3. Required Deliverables
​Full Ansys Project Files: Including geometry, mesh, and solution settings.
​Analytical Plots:
​Maximum Von Mises Stress vs. Frame Spacing.
​Total Structural Weight vs. Frame Spacing.
​Maximum Deformation vs. Weight.
​Optimization Result: A clear recommendation on the arrangement that provides the best weight-to-strength efficiency.

​4. Freelancer Skills
​Proficiency in Ansys Mechanical (Workbench).
​Background in Mechanical, Structural, or Marine Engineering.
​Ability to generate clean, professional stress contour plots and data charts.
