船舶推进轴系扭转─轴向耦合振动响应曲线的分析

Analysis on Coupled Torsional-axial Vibrations of Ships Propulsion Shafts

本文结合七条船舶推进轴系的轴向振动实测曲线，对其扭转-轴向耦合振动的响应曲线进行了分析，从而对扭转-轴向耦合振动的规律进行了有意义的探索。

An analysis of the coupled torsional-axial vibration of propulsion shaftings for several ships ismade and the regularity of ship coupled torsional-axial vibration is studied and discussed in thispaper.
