ANSYS Van Body Stress Analysis
Budget: €250 – €750 EUR
I am looking for a skilled FEA (Finite Element Analysis) Engineer to perform a structural comparative study between two variants of a van's rear body structure. The main objective is to verify that both designs exhibit similar deformation and Von Mises stress levels under three different load cases.
Inputs Provided:
Model A (Baseline): Half-body CAD model of the van's rear structure (as shown in the attached image), prepared for symmetric mirroring.
Model B (Reinforced): The same body structure but including two upper joining ribs and additional reinforcements.
Software Requirements:
ANSYS Mechanical (Version 2024 R2 or lower). Note: Delivery of the native archive file (.wbpz or project folder) is mandatory.
Scope of Work:
Geometry & Meshing:
Apply a symmetric mirror to complete the full rear body structure for both models.
Generate a high-quality surface mesh (shell elements for sheet metal) ensuring proper connectivity, normal orientations, and alignment at the symmetry plane.
Setup & Boundary Conditions:
Define appropriate material properties (Steel/Aluminum - to be specified).
Apply realistic constraints (simulating the connection to the rest of the vehicle chassis).
Set up 3 distinct load cases (forces) which will be provided (e.g., torsion, bending, or specific point loads).
Analysis & Comparison:
Run linear static structural analyses for both models across all 3 load cases.
Compare Total Deformation and Von Mises Stress plots between Model A and Model B.
Deliverables:
Fully functional ANSYS project files (Geometry, Mesh, and Setup).
A concise Technical Report (PDF) summarizing the mesh quality metrics, boundary conditions, and comparative results (side-by-side contour plots of stress and displacement, percentage differences).
Skills Required:
ANSYS Mechanical / Workbench
Finite Element Analysis (FEA)
Structural Engineering / Automotive Design
Mesh Generation (Shell/HyperMesh/ANSYS Meshing)
Crucial Note on CAD Cleanup & Midsurfacing: > CAD simplification, clean-up, and defeaturing are mandatory and highly encouraged. The original 3D geometry contains complex production features that will cause midsurface extraction and high-quality shell meshing to fail if left as-is. You are expected to remove small fillets, non-structural holes, and tiny features to ensure a clean, continuous sheet-metal mesh without compromising the main structural stiffness. Please factor this geometry preparation into your initial bid.
IMPORTANT - ANTI-BOT FILTER: > To prove you have read and understood the entire project scope, please start your proposal with the exact word "ANSYS-MIDSURFACE" and briefly mention in your first sentence what strategy you will use to clean up the geometry before meshing. Failure to do this will result in immediate rejection of your bid.
