A Software for The Design and Optimization of Bolted Joints Under Eccentric Load

Bolted joints are among the most reliable and common methods of securely joining objects. The design and analysis of these joints is important for speed and efficiency. Efficient systems can be created by optimizing properties such as size, quantity, material and safety. In this study, analysis-based design and optimization of bolted joints subjected to eccentric loads is addressed. In line with this goal, an interactive software named “DESOPT BJ” was developed using C# programming language in Visual Studio development environment. A user-friendly graphical interface with graphical designs was designed and a customizable integrated database was established. Template joint types with different bolt numbers and placements can be selected from the software. Design parameters and load conditions for the joint are taken as input. The software performs calculations within the scope of the database and optional results for the design are found by filtering according to the targeted factor of safety. In the optimization process, optimum results are obtained by applying diameter, strength and safety constraints for bolts and minimum and maximum conditions for these constraints on the optional results. The results include metric bolt, grade, yield strength and factor of safety parameters for the bolted joint. Optional and optimum results for bolted joints are calculated for template designs, minimum user input and database. Real-time software provides instantaneous responses. The graphical user interface adds interactivity and practicality to the design and optimization process. User workload is minimized and significant time savings are achieved. Software results and theoretical solutions offer 100% strong compatibility.
