Title: Performance Analysis of Preloaded Bolted Connections: Experimental and Theoretical Study
Keywords: Preloaded bolted connection, friction coefficient

Abstract: This study investigates the performance of a preloaded bolted connection in mechanical engineering applications, focusing on determining the maximum allowable load with a specified safety factor. The connection comprises two S355 steel plates joined by high-strength M16 bolts in oversized holes, with molybdenum disulfide lubrication and sandblasted surfaces to optimize friction coefficients. Experimental testing demonstrated the joint’s ability to withstand significant loads without slip, exceeding design expectations. Theoretical analysis using Autodesk Inventor confirmed the reliability of the design, highlighting the importance of accurate friction parameters. The study provides insights into designing preloaded bolted connections for high-load applications, emphasizing the role of surface treatment and lubrication of the bolts in ensuring consistent performance.
