两栖作战武器横摇动力学分析

Dynamics Analysis of Amphibious Combat Weapon Roll Motion

横摇动力学是两栖作战武器的一个重要研究内容,横摇是两栖作战武器在通过内陆江河水系和抢滩登陆作战中存在的重要问题,它直接影响着乘员和装备的战斗力发挥.依据船舶的有关理论,对两栖作战武器的水上横摇运动动力学进行了分析研究.首先对两栖作战武器进行了受力分析并给出了横摇动力学方程,研究了两栖作战武器横摇无因次幅频特性和相频特性与横摇调谐系数和无因次阻尼衰减系数之间的关系,可供两栖作战武器设计参考借鉴.

It is well know that roll motion of amphibious combat weapon in regular wave will severely affect the battle effectiveness of crew in the amphibious combat weapon and the fire accuracy.In this paper,a roll motion dynamics of amphibious combat weapon in regular wave is developed based on the wave resistance theory for ships.Damping influence on the amplitude and phase angle in the frequency region near resonance.Technical measure is given for antiroll,and it can be referenced by amphibious combat weapon designer.
