摘要

本文研究了曲轴扭振与低速柴油机机体振动之间的耦合效应。采用有限元方法，建立了低速柴油机的振动响应模型。有限元模型计算结果与试验结果吻合较好。详细讨论了低速柴油机扭振引起的附加力矩。采用有限元模拟方法研究了考虑扭转振动影响的低速柴油机的振动响应。通过分析扭振对发动机机体振动的影响，表明曲轴扭振对机体振动有重要影响。研究结果可为低速柴油机的振动预测提供有益的理论指导。

Analysis of torsional vibration effect on the diesel engine block vibration

In this paper, the coupling effect between the crankshaft torsional vibration and the low speed diesel engine block vibration is investigated. Using finite element method (FEM), a model of low speed diesel engine is established to study the vibration response. The mode results of FEM agree very well with the test. The additional torques acting on the low-speed diesel engine caused by torsional vibration are discussed in detail. The vibration response of the low-speed diesel engine considering the effect of torsional vibration is studied using FEM simulation. By analyzing the effect of torsional vibration, the results demonstrate that the crankshaft torsional vibrations have important effects on the engine block vibration. The results from this study can provide useful theoretical guidance to predict vibration of low-speed diesel engine.
