摘　　要：本文以39000DWT散货船轴系扭转振动计算为实例,简要介绍调整轴系中间轴及螺旋桨轴的参数、匹配调频轮及转动飞轮的转动惯量来改变其固有频率,降低扭转应力峰值,以满足船级社规范的要求,达到控制扭振的目的,消除船舶营运中轴系扭转振动故障的风险。In this paper,the calculation of shafting torsional vibration for 39000 DWT bulk carrier is taken as an example,the natural frequency is changed and torsional stress is reduced by adjusting the parameters of the middle shaft and propeller shaft,matching the moment of inertia for tuning wheel and flywheel,so as to meet the requirements of the classification rules,achieve the purpose of controlling torsional vibration and eliminate the risk of shafting torsional vibration failure in ship operation.
