摘　　要：针对某船双机并车柴油机推进系统,进行轴系扭转振动当量简化,同时考虑盖斯林格联轴器扭转刚度、阻尼随着转速变化而变化的特性,对轴系扭转振动自由特性及强迫振动特性进行分析,说明盖斯林格联轴器的变特性不可忽视,并经实船测试验证计算结果的正确性。Aiming at the CODAD propulsion system, it is to simplified shafting torsional vibration equivalent. Considering the torsion stiffness and the characteristics of damping changing with rotational speed changing of the Geislinger coupling, the free torsion vibration and the force torsion vibration of the shaft are analyzed. The result can tell that the variable characteristics are too important to be neglected. Besides, the calculation result are verified by the test on-board.
