摘要
本文根据时域最小二乘原理,应用Newton-Raphson法识别了系统的模态参数,所得结果与CRAS系统分析结果相比,误差极小。
The model paramenters of vibration system are identified based on the least squares method and Newton Raphson method. The error of the calculated results as comparaed with the analytical results of CRAS system is very little. It shows that the reliabitity of this method is satisfactory.
