【摘要】 针对轧机传动系统结构复杂性和影响因素的复杂性等原因造成的某些关键点不可测的问题,建立基于盲源分离的轧机扭振测量模型,实现不可测点的扭振测量。轧机实际现场扭矩测试和数据分析处理结果验证了理论推导的正确性。这为轧机现场监测中一些不易布置传感器关键点处的物理量测取提供了理论依据和技术支持,通过编制程序可以实现轧机在线系统监测和故障分析,从而确保轧机正常平稳运行。更多还原

【Abstract】 For the key point unmeasured problem which was caused by the structure complicacy and infection factor complicacy,the soft measuring model was established and the torsional vibration measurement of the unmeasured point was realized.Analysis and processing data of actual torque measurement on the rolling mill’s main drive system verified the correct of the deriving course of the theory.Based on the solution,it can program composition for implement on-line monitor and fault diagnosis on main drive shaft and then guarantee the rolling mill even running.更多还原
