AI Technical Summary
The right-angle welded structure between the bulkhead and the bottom of early yachts is prone to stress concentration under dynamic loads, which can lead to weld cracking or fatigue failure of the base material, and may cause leakage or structural deformation during long-term use.
The structure employs a multi-L-shaped plate structure, including a first L-shaped plate, a second L-shaped plate, and a third L-shaped plate, which are welded sequentially from the corner where the bulkhead and the hull meet. A transition rounded corner is provided, and the multi-L-shaped plates disperse local stress to a wider range of bulkhead and hull structures.
It significantly improves the bending and shear resistance of the area where the yacht's bulkhead connects to the hull, avoiding fatigue cracks and structural deformation caused by single-point overload.
