摘要
本文就瞬态多自由度振动信号阻尼比的获取进行了研究，指出了用最大熵谱法一次计算得出多个模态阻尼比的新方法。阐明求取阻尼比的理论与计算方法，并用计算机进行了仿真计算与分析，取得了良好效果。
In this paper the authors make an approach how to obtain the damping ratio of instantaneous vibrating signals with multi-freedom, put forward a new method for getting the damping ratio of several modalities by once-through calculation with maximum entropy spectrum method and expounded the theory and calculation method for achieving damping ratio, thus good results were obtained through emulation computation and analysis with computer.
