中文摘要:
      安装在直升机桅杆顶部的雷达需要进行轻小型设计,同时又要适应严酷的力学环境,减重与提高系统的刚性通常是一对矛盾。为了在轻小型状态下提高系统抗力学环境的能力,需要对此类雷达进行动力学分析及主动振动抑制方法的研究。文中利用 Kane 方法推导了直升机载雷达的动力学理论模型,验证了模型的正确性,求解了直升机载雷达的振动变形情况,给出了主动抑振方法,求解了抑振效果,为直升机载雷达的主动振动抑制研究提供了理论基础。
英文摘要:
      The radar mounted on the top of helicopter mast requires a lightweight design and has to adapt to strict mechanical environment at the same time. There is usually a contradiction between weight reduction and system rigidity improvement. It is necessary to research the dynamic characteristic and active vibration control methods of this kind of radar to improve the system's resistance ability against mechanical environment in the lightweight state. In this paper, the dynamic theoretical model of the helicopter-borne radar is derived by Kane method and the correctness of the model is verified. The vibration deformation of the helicopter-borne radar is solved, the active vibration suppression method is presented and the damping effect is solved. It provides a theoretical basis for the research on the active vibration suppression of the helicopter-borne radar.
