摘要
依据电测实验结果，分析了初轧机万向接轴扭振的平稳性，提出了扭振放大系数Ｋ_ｄ的概率分布分析模型，建立了扭振的ＭｏｎｔｅＣａｒｌｏ模拟模型，最后给出了应用实例。结果表明，Ｋ_ｄ模拟数据同实测数据一致。
Based on the measured Torque spectra, the stability about Torque vibration is evaluated. The procedure to analyze the probability distribution of K_d, the Torque amplifying coeffient,is developed by Mote Carlo approach.The example of application proves that a good correlation is obtained between the simulated distribution and the experimental results.
