| 摘 要： | 从静态、动态和耦合振动等几方面对人们所关注的长行程船用柴油机轴系轴向振动加剧的机理进行了深入的理论分析，并通过实测结果加以证实。指出了随着柴油机行程加大和爆力压力的提高，会使轴向振动的平衡振幅加大，这是轴向振动加剧的主要原因。

| Abstract: | The reasons of serious axial vibration in low-speed long-stroke marine engine areanalysed by means of deflection of the crank and calculation results of axial vibration withdifferent ratio S/D and the effect of torsional- axial coupled vibration. SOme measuring examplesof axial virations in engines with different ratio S/D are also presented. |
