轴系扭振模型参数的修正

Correction of Model Parameters For Torsional Vibration of Shafts

本文提出了一种轴系扭振模型参数的调整方法.通过改变轴系的某些特定参数,可将指定的若干阶扭报频率调整到某几个确定值.从而为轴系调频以及建立更符合实际情况的数学模型,提供了.种实用而有效的方法.用这一方法对扭振模型试验台进行了计算.经调整后,计算模型的计算频率同实测值完全一致.

A method for adjusting parameters of torsional shaft vibration models is proposed. By varying some specific parameters of shafting, torsional vibration frequencies of specified orders can be shifted to definite values, herewith providing a practical and effective way for tuning and establishing mathematical models that would comply with actual conditions. A torsional vibration test rig model has been calculated by using this method. After adjustment, calculated frequencies harmonize well with actual test values. Figs. 6,tablel and refs. 4.
