Development and analytical validation of a design tool for optimizing the number, size and flange geometry of bolts used to assemble cylindrical bodies

This thesis presents the development and analytical validation of a new design tool specifically designed to optimize the number, size and flange geometry of bolts used in the joining of cylindrical bodies. Bolts play a critical role in structural integrity, especially in cylindrical body assemblies where factors such as load distribution, stress concentration and overall stability are crucial. However, the optimal configuration of bolts is a multifaceted problem influenced by several factors including material properties, geometric constraints and mechanical requirements. The research begins with a comprehensive review of existing methodologies and tools used in bolted joint design, identifying gaps and limitations. Utilizing the knowledge gained from this review, a systematic approach is proposed for the development of an integrated design tool that takes into account the complex interaction between bolt parameters and structural performance. The tool incorporates advanced computational algorithms and finite element analysis techniques to efficiently simulate and evaluate different bolt configurations. Rigorous analytical validation procedures are carried out to ensure the accuracy and reliability of the design tool. The results demonstrate the tool's effectiveness in predicting bolt behavior under varying conditions and its ability to produce optimal designs that meet specified performance criteria. Furthermore, the thesis explores the practical implications of using the developed tool in real-world engineering applications. Several studies are presented to demonstrate the versatility of the tool and its applicability in different scenarios, highlighting its potential to streamline the design process, reduce costs and improve overall structural integrity. In conclusion, this research contributes to the advancement of bolted joint design by providing a comprehensive and robust tool to optimize bolt configuration in cylindrical body assemblies. By integrating computational modeling with analytical verification, the developed tool will provide engineers with a valuable resource to achieve optimal structural performance while addressing the complex challenges associated with bolted connections.
