- Optimization and analysis of heavy duty steel packaging structure using numerical finite element analysisPublication . SILVA, LUCAS LAGES; Campilho, Raul Duarte Salgueiral GomesThe increasing demand for safer, more sustainable, and more efficient transport solutions is driving innovation in the packaging industry, particularly in the context of heavy and voluminous cargo. Despite the standardisation of pallets, discrepancies persist in the protection of large equipment, necessitating the development of more robust and adaptable structures. This thesis focuses on developing and optimising a heavy-duty steel packaging structure for the safe and efficient transportation of heavy and oversized shafts. The project addresses critical challenges relating to load securing, operational safety, and logistical efficiency. The research methodology is based on a structured approach incorporating a literature review, design synthesis and validation, and iterative structural optimisation using Finite Element Analysis (FEA). Design Science Research (DSR) was adopted to ensure a systematic, application-oriented design process. Ashby’s method was used to select structural solutions that focus on strength, durability, and manufacturability. Several design iterations were developed to accommodate various handling and transport conditions, such as lifting, stacking, and forklift compatibility. The final packaging solution incorporates functional elements such as adjustable axial brakes, lashing points, forklift entry channels, and stackable elements to improve usability and adaptability. FEA simulations confirmed compliance with mechanical resistance criteria, particularly von Mises stress limits, thereby ensuring the structural integrity of the solution. Furthermore, the packaging design contributes to sustainability goals by reducing long-term costs and minimising environmental impact through extending the product's life and increasing its potential for reuse.
