Input
Prompt
Create a precise 3D CAD model of a single industrial crane hook based on a standard curved “C” profile as shown in the reference image. The model must be fully dimensioned in millimeters and suitable for finite element stress analysis (FEA). Overall Dimensions (in mm): Total height (top shank to hook tip): 300 mm Throat depth (horizontal distance from inner curve to tip): 120 mm Inner radius (main load-bearing curve): 70 mm Outer radius (corresponding outer curve): 110 mm Cross-sectional thickness (constant through hook body): 40 mm Hook width (out-of-plane thickness): 50 mm Top shank diameter (cylindrical vertical portion): 60 mm Fillet radius at shank-to-curve transition: 20 mm Geometry Requirements: The hook should follow a smooth circular arc between inner radius (70 mm) and outer radius (110 mm). Maintain uniform cross-section throughout the curved portion. All transitions must include smooth fillets (minimum 10–20 mm) to avoid stress singularities. The inner curve and outer curve must be concentric along the main load arc. Trapezium Feature (For Stress Analysis Region): Insert a trapezium-shaped cut or embedded region located within the curved section between the inner and outer radii. The trapezium must: Be positioned along the mid-arc of the hook (approximately 45° from vertical centerline). Have a top base of 40 mm, bottom base of 60 mm, and height (radial direction) of 25 mm. Be aligned radially between the inner and outer surfaces. Occupy only a portion of the curved section — it must not span the entire curvature. Leave at least 20 mm material clearance from both inner and outer boundaries. The trapezium should be clearly defined as a separate surface or body for stress evaluation. Modeling Conditions: Model must be solid (not surface-only). Ensure geometry is clean and watertight for meshing. Maintain dimensional accuracy for theoretical stress calculations. Use sharp definition for trapezium edges unless otherwise specified.
