Numerical Simulation and Experimental Research of Torsional Vibration of Shafting for ND_5 Type Locomotive

本文提出了在拍系存在大阻尼情形下综合阻尼系数的计算方法，并运用该方法对ND5型机车轴系扭转振动进行了数值模拟。模拟计算与试验结果有较好的一致性．另外，本文还对影响轴系扭振计算精度的多种因素进行了分析和讨论。

In this paper a numerical method of synthetic coefficient under large haping of shafting isproposed and applied to torsional vibration simulation of the shafting for type ND5 locomotive. It hasbeen shown that the numerical simulation corresponded well with the measurement. In addition, somefactors affecting the accuracy of computation of shafting torsional vibration are analyzed and discussed.
