摘要
分析了减振器和弹性联轴节在机车柴油机轴系扭振中的减振特性减振器能显著地减小扭振振幅和附加剪应力，弹性联轴节可以明显地改变低频固有频率和临界转速，对减小振幅和应力有效果。
Researches the damp function of the damper & elastic coupling in torsional vibration for shaft system of diesel engine of the locomotive.The damper can reduce notably the amplitude of torsional vibration and additional shear stress.Elastic coupling can change evidently lower natural frequency and critical rotion speed.It can reduce notably the amplitude and the stress,but can increase the amplitude of some nodes and the stress of some shaft ranges.
