转炉模型的动态力识别

Identification of Dynamic Environment of a Converter

利用频谱分析后得到的响应信号和传递函数在频率域内对转炉模型做了动态力识别。首先应用传递矩阵求逆法,识别出给定的动态力——脉冲力和正弦力。然后由付氏逆变换求出时间域的力函数并给出它的波形.

In this paper the identification of dynamic forces is made byobtaining respondent signal and transfer function for a converter model infrequency domain after analysis of frequency spectrum.First,by the inversealgorithm of transfer matrix,the given dynamic forces—pulse force andsine force—have been identified.Then,the force functions are solved byinverse Fourier transformation and their waves are drawn in time domain.
