摘　　要：通过对实际的非共振固有振动的振幅和波形的实验分析研究,证明了一种力学系统的倍频非共振固有振动的特征与谐波共振的区别.这种倍频非共振固有振动状态与系统阻尼系数有直接的关系.阻尼系数的大小,直接影响倍频非共振固有振动的强弱和波形特征.Experimentation research showed that the damping coefficient of a mechanics vibration system had the major effects on the waveform of multiple-frequency non-resonance natural vibrations. It was proved that the non-resonant natural vibration and harmonic resonance are two kind of different natural vibration.The experiment data and experiment techniques was given in this paper

关 键 词：倍频非共振固有振动 非完全强迫振动系统 谐波共振 阻尼系数
