长冲程船用柴油机轴系扭转-轴向耦合振动(二)─—耦合振动典型实例剖析

Coupled Tortional-axial Shafting Vibration for Longstroke Marine Diesel(Part 2)──Case Study on Resonance Curves

本文通过7则典型的船用二冲程低速柴油机推进轴系实测的轴向振动实例的剖析，研究了扭转－轴向耦会振动问题，探求解决问题的途径，有助于船舶管理人员了解和熟悉轴系轴向振动的新问题。

An analysis of vibration test results of propulsion shafts is made for seven typical marine lowspeed long-stroke diesels. The coupled tortional-axial vibrations are investigated and the measures for improving the coupled vibration is suggested.
