Study on Influence of Structural Arrangement of Recoil Mechanism on Muzzle Vibration of Gun

doi:10.3969/j.issn.1000-1093.2013.10.002

Abstract

Abstract: Muzzle vibration is one of the most important factors influencing the firing dispersion of gun. Inorder to study the technical approaches to reducing the muzzle vibration, a launch dynamic model of alarge caliber gun is established based on the nonlinear finite element theory, in which the contact impactbetween interacting components is considered. The influences of different fixed forms and different locations of the counter-recoil mechanism and recoil mechanism on muzzle vibration are studied by numericalcomputation, and the load transfer rules of the guns with different structural arrangements are analyzed.The optimal structural arrangement is determined by contrastively analyzing the muzzle vibration responses. The results can provide theoretical reference to the overall structure design of the gun systems.

Key words: ordnance science and technology, nonlinear finite element, muzzle vibration, contact im- pact, load transfer rule
