Structural Simulation
- Structural simulation is a powerful tool for engineers to predict and understand the behavior of complex structures, allowing them to optimize designs, improve performance, and ensure structural integrity.
- Structural simulation, also known as structural analysis or finite element analysis (FEA), is a computational method used to predict how a structure will respond to various loading conditions.
- It is commonly used in engineering to design and analyze structures such as bridges, buildings, aircraft, and vehicles.

Structural Design for Hitch
- Analyze as per the SAE J684.
- This SAE Standard includes couplings, hitches, and safety chains used in conjunction with all types of trailers or towed vehicles whose Gross Vehicle Weight Rating (GVWR) does not exceed 4540 kg (10 000 lb).
- This includes such types as utility, boat, camping, travel, and special purpose trailers which are normally towed by conventional passenger cars, light-duty commercial vehicles, light trucks, and multipurpose passenger vehicles.
Structural Design for Boats
Designing the structure of a boat requires careful consideration of various factors to ensure safety, performance, and durability.
Hull Design: The hull is the primary structural component of the boat, providing buoyancy and supporting the weight of the vessel. Design considerations include hull shape, size, material selection, and construction method. Common hull materials include fiberglass, aluminum, wood, and composite materials like carbon fiber.
Design the hull, deck, bulkheads, and other structural components to withstand the stresses and loads encountered during operation, including wave impacts, wind forces, and cargo weight. Use structural analysis techniques such as finite element analysis (FEA) to assess stress distribution and ensure sufficient strength and stiffness.
