摘　　要：设计一个综合性振动参数特性测量实验,对振动波形图法、半功率点法、李沙育图法3种实验方法分别进行了理论分析与比较,阐明了3种实验方法的各自适用性,即振动波形图法适用于阻尼比小于0.3时的振动系统;半功率点法适用于阻尼比小于0.5的小阻尼比系统;李沙育图法适用于阻尼比较大的系统。从而得出,在不同阻尼比情况下应该采用的实验方法。A comprehensive vibration parameter characteristic survey experiment was designed to carry on the theoretical analysis and compare with the vibration waveform diagram, half-power point method, Lissajous diagram. It points out that, the vibration waveform diagram is suitable for the vibration system whose damping ratio is smaller than 0.3 ; half- power point method for suitable in small damping ratio system whose damping ratio is smaller than 0.5; Lissajous dia- gram for relatively large damping system. Thus obtains the experimental technique which can be use in different damping ratio situation.
