The primary motivation for this paper is to present a reliable and convenient technique for the modeling and computation of the DVA-beam system. Rapid modeling and simulation of the DVA-beam system are of great importance for dynamic performance, evaluation, and finally, the structural design. The dynamic vibration absorber (DVA) has a broad application background in slender structure vibration reduction, such as in machine gun systems, micro actuators, and so on. © 2015, The Korean Society of Mechanical Engineers and Springer-Verlag Berlin Heidelberg. Results show that muzzle vibration and structure deformation are reduced and firing accuracy is remarkably improved. Dynamic analysis, exterior ballistics calculation, and experimental test are conducted to verify the effectiveness of the proposed method. Based on topology optimization results, the revised model addresses all structural and manufacturability concerns. The frequency is maximized by subjecting topology optimization to mass constraints. The objective function is the frequency of the main vibration mode confirmed by modal and transient dynamic analyses. This paper presents an effective and efficient method that accomplishes these tasks. Eigenfrequency optimization based on topology is an emerging vibration suppression technique that reduces structural vibration and stabilizes a machine gun system. Studying the dynamic characteristics of the machine gun system and reducing its vibration response are crucial. Structure vibration is known to influence the firing accuracy of a machine gun system.
