Space Frame Chassis Design and FEA Validation This project involved the complete design and structural validation of a lightweight tubular space frame chassis for a race car. The chassis was developed in SolidWorks with a focus on achieving high torsional stiffness, low mass, and compliance. The frame geometry was optimized to accommodate the suspension system, powertrain, steering assembly, and driver cockpit while maintaining structural efficiency. A detailed Finite Element Analysis (FEA) was performed in ANSYS Mechanical to evaluate the structural behavior of the frame under realistic operating conditions. Multiple loading scenarios were investigated, including: - Front and rear suspension loads - Torsional loading - Combined static loading cases - Structural deformation assessment - Von Mises stress distribution - Safety factor evaluation Key Features: - Full 3D CAD modeling in SolidWorks - Welded tubular space frame design - Formula Student chassis architecture - Structural optimization for strength-to-weight ratio - Finite Element Analysis (FEA) in ANSYS Mechanical - Stress, deformation, and stiffness assessment - Engineering documentation and design validation Project Specifications: - Wheelbase: 3050 mm - Overall Length: 3450 mm - Maximum Width: 1606 mm - Frame Height: 750 mm - Main Material: Aluminum Alloy - Driver Safety Cell: Steel 20 - Frame Weight: 65.4 kg
