摘要
为了研究火炮同心式电涡流阻尼器对炮口振动特性的影响规律,基于非线性有限元理论,分别建立了同心式布置和偏置式布置制退机的火炮发射动力学模型,通过数值模拟对比研究2种电涡流阻尼器布置方案对炮口振动的影响,分析了前后衬瓦受力规律的变化,结果表明:采用制退机同心式布置方案,炮口水平角位移和高低角位移的最大值分别为偏置式布置方案的43%和38%;高低机齿弧、前衬瓦和后衬瓦所受最大接触力分别为偏置式布置方案的29%、24%和17%。
To research the influence of concentric eddy current damper on muzzle vibration characteristics of artillery,based on nonlinear finite element theory,the dynamic models of gun launching with concentric arrangement and offset arrangement recoil brake were established to study the influence of two recoil brake arrangement on muzzle vibration and analyze the change of contact force on front and rear lining tiles by numerical simulation.The results of numerical analysis show that the maximum horizontal and high-low angular displacements of muzzle are 43%and 38%of offset layout respectively and the maximum contact forces of arc and gears,the front and rear liners of cradle are 29%,24%and 17%of the offset layout respectively.
