【摘要】 为降低复杂信号模型识别困难,采用把线性参数和非线性参数分开识别的方法.该法可用于对立辊轧机冲击振动加速度信号的识别.通过识别到的加速度信号解析式,可得到振动速度及振动位移.该解析法具有较高的消噪能力,并可识别出高精度的轧机系统振动模态参数.更多还原

【Abstract】 For lowering the difficulty of identifying the complicated signals,the linear and nonlinear parameters in the simulation models have been separated and recognized with two different methods.This means has been successfully used to identify the acceleration model of a shock response signal for the vertical millers.Through the analytical expressions of the acceleration signals,the vibration velocity and vibration displacement signals can be easily reached.The method presented in this paper has higher de-noising ability,and the accurate modal parameters can also be identified.更多还原
