摘要/Abstract

摘要： 大口径火炮炮口振动响应是影响火炮射击密集度的关键因素之一。为了研究减小炮口振动的技术途径,基于非线性有限元理论,考虑机构之间的接触碰撞关系,建立了某大口径火炮样机的发射动力学模型。通过数值计算研究了复进机和驻退机的不同固定方式和不同布置位置对炮口振动的影响规律,分析了不同结构布置下载荷的传递规律。通过对炮口振动响应量进行分析对比,确定了较优的结构布置方案。研究结果对该类火炮的总体结构设计具有一定的参考价值。

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
