The axial vibration of the crankshaft was first introduced in 1940 and related studies were conducted in the 1960s. An axial vibration countermeasure of a de-tuner, similar to a thrust bearing, was applied at an early stage. After the first and second oil shocks in the 1970s, MAN Energy Solutions developed the fuel-saving long-stroke MC engine and they began to apply the axial vibration damper (AVD) in earnest. Around that time, WinGD also developed the RTA engine and started to apply AVD. They installed the AVD as a separate structure on the crankshaft end. Currently, a compact structure is applied to all two-stroke low-speed diesel engines for ships, regardless of the number of cylinders. However, hull vibration caused by thrust variation force resulting from axial vibration is occasionally a problem. There have been studies on the damping adjustment method of AVD to reduce the thrust variation force in specific operation areas. In this paper the AVD was modeled by various functions between a damper and de-tuner. The axial vibration characteristics of a propulsion shaft system using the research model 11G90ME engine were investigated through theoretical analysis and measurement data according to the AVD modeling method. The results indicated that the suitable modeling method of AVD was the combined function of damper and de-tuner.
