<p>Gatling guns, known for their high firing rates and destructive force, generate substantial vibrations in turret systems during operation. Understanding and mitigating these vibrations is essential for maintaining the performance and longevity of modern weapon systems. This paper presents a detailed methodology for analyzing the vibration characteristics of turret systems equipped with Gatling guns. A finite element analysis (FEA) model was developed, and input forces including axial, tangential, and torque were modeled based on ballistics theory. Transient analysis was conducted using these inputs, and the results were validated through firing experiments that measured vibration signals in the actual system. By comparing the simulated data with experimental results, the reliability and accuracy of the FEA model and input parameters were confirmed. This study provides critical insights into improving the structural integrity and operational performance of turret systems, offering a foundation for advanced vibration reduction strategies in future weapon system designs.</p>
