摘　　要：对冰区船舶推进轴系时域扭振建模方法进行阐述,归纳了扭振计算的流程,并对计算中的关键问题及影响因素进行了探讨。应用Newmark-β逐步积分法和MATLAB求解工具,进行了轴系瞬态扭振仿真计算。螺旋桨轴最大扭矩幅值的计算结果与国外计算报告的相对偏差为0.82%,验证了计算方法和程序的正确性,可为冰区船舶柴油机推进轴系瞬态扭振计算提供参考。A torsional vibration modeling method in time-domain for propulsion shaft of the ice-class vessel is elaborated and calculation process is summarized. Key problems and influencing factors in the calculation are discussed. Numerical simulation of transient torsional vibration is carried out by using Newmark-β stepwise integration method and MATLAB solver tool. Difference of the maximum torque amplitude of the propeller＇s shaft between the calculation and reference [21] is 0.82%, which verifies the correctness of the calculation method and the program, and provides a reference for the calculation of transient torsional vibration of diesel engine propulsion shafting in ice-class vessel.
