ANSYS Warren Truss Dynamics
Budget: ₹600 – ₹1,500 INR
I need a complete finite-element model of a Warren through truss bridge built in ANSYS (Workbench Mechanical or APDL). The task covers geometry creation, material assignment, boundary conditions and, most importantly, a dynamic study that captures wind and traffic effects.
For wind, please implement a realistic fluctuating pressure profile; for traffic, model moving axle loads that travel the bridge length with appropriate speed and spacing. Time-history or transient structural analysis is preferred so that true stress-strain and displacement histories can be extracted.
I have only a broad idea of where sensors should sit—mid-span, panel points near supports, and a few along the top chord—so I will rely on your structural-health-monitoring experience to pin down the exact node IDs and coordinates that maximise modal observability and cover critical stress zones.
Deliverables
• ANSYS project file with fully defined geometry, materials, constraints and both dynamic load cases
• A concise report (PDF or Word) containing model assumptions, mesh stats, natural frequency summary, peak responses and plots for each sensor location
• Table (CSV or Excel) listing final sensor coordinates and corresponding result channels (displacement, velocity, acceleration, stress)
• Screenshots or animations that clearly illustrate load application and deformation
Acceptance criteria: model solves without errors, results converge on mesh refinement, and outputs match textbook expectations for a Warren truss under comparable loading.
Feel free to use any reputable ANSYS plugins or scripting (MAPDL, ACT, Python) that speed up the workflow, as long as everything is documented so I can reproduce the runs later.
