| 摘 要： | 本文根据多自由度系统受单一载荷作用的特点,将载荷识别的理论公式简化为只要依据系统任意点的响应信号和一个对应的频响函数即可运算,并在使用HP3562A 动态信号分析仪的实验中证明具有很好的识别精度。此种识别技术还可推广用于识别实际上不是作用于某点的当量载荷。

| Abstract: | According to the characteristics of multi-degree-of-freedom system affedted by single force,the theoretical formula of the load identitication is simplified to the form operated only with a respmse signal at any point and its corres- ponding frequency response function of the system.It can be porformed with HP3562A dymamic signal analyzer.As shown in our experiments,agood precision can be achieved.This technique can also be extended to the identi- fication of the equivalent load that does not directly act on the point. |
