Structural_Analysis_of_Roller_Coaster_Rails

This project investigates roller coaster rail designs using Finite Element Analysis via ANSYS and experimental optimization through the Taguchi Method. The goal is to identify the most structurally efficient rail configuration under different load scenarios

🛠 Tools Used

• ANSYS Workbench for structural simulations
• Taguchi Method for design of experiments (DOE)
• SolidWorks for CAD modeling

📐 Rail Design Geometries

🧪 First Design

Standard geometry with uniform curvature.

🧪 Second Design

Modified curvature to reduce deformation.

🧪 Third Design

Optimized for structural strength and aesthetic.

📊 Stress & Deformation Results

✅ Best Case – Third Design (AISI 1020, 70 MPa)

Minimal deformation and stress levels.

❗ Worst Case – Third Design (AISI 1020, 150 MPa)

Rail integrity remains intact under maximum load.
