| 摘 要： | 针对系统动态特征参数的测试与计算的问题，分析了常用的时域响应法和频率响应(共幅值)法使用的局限性，根据系统幅频特性和相频特性关系式，推导出一种动态特性的测试计算方法。该方法建立在系统频率响应基础上，兼顾了幅频和相频二者信息，其测试和计算简便，不仅适合阻尼较小的系统，也适合阻尼比较大的系统。

| Abstract: | Aimed at system dynamic parameter test and calculation method, the paper analyzes limitation of the usual time respond method and frequency respond (resonance range method) method and deduces a kind of test and calculation method for dynamic parameter based on the relation between the amplitude frequency respond and phase frequency respond. The method is based on the system frequency and combines amplitude frequency and phase frequency respond. This method proves very easy for experiment and calculation. The method is suited for both the little resistance system and bigger resistance system. |
