摘　　要：转管武器射击时,其枪机本体与枪机座之间的轴承游隙,依据非线性动力学特征-混沌运动,经过混沌计算对转管武器射击的精度有很大的影响。弹丸运动的质量偏心对系统的动力学特性有一定的影响,一定的偏心会使枪机本体(转子)的振动加剧、混沌运动区域变长,但是枪管套箍可以采用偏心来减少影响。对此可以对3000 m射击的高射速转管武器提出了间隙大小的指导。The bearing clearance between the barrel gun body and the gun seat,and the nonlinear dynamic characteristic of chaotic motion,have a great influence on the firing accuracy of the gatling gun after chaotic calculation.The mass eccentricity of projectile motion has a certain influence on the dynamic characteristics of the system.A certain eccentricity will aggravate the vibration of the gun body(rotor)and lengthen the chaotic motion region,but the barrel hoops can be used to reduce the influence of eccentricity.It can be used to guide the clearance size of the high speed Gatling gun fired at 3000 m.
