摘　　要：文中探讨了多管火箭系统振动的变阻尼控制问题。文中建立了某型火箭炮的动力学模型,结合该炮结构及发射要求提出了用可变电磁阻尼器来进行振动控制,并建立了相应的模型。动力学仿真表明,通过改变其阻尼系数,可有效抑制不同峰值的振动,变阻尼控制的效果较好。This paper focuses on the problem of the vibration control of MRLS-variable damper control.A dynamic model is founded based on the MRLS.Based on the structure of the MRLS and the launch requirements,a variable electro- magnetic damper is presented to control vibration and a damper model is set up.The simulation of dynamics shows that the variable damper control can work effectively to control the vibration through variable damper value,which indicates that variable damper control is effectively.
