Abstract

To study the dynamic characteristics of marine compound NC machine, the machine motion coordinate system and the layout scheme were revealed based on the analysis of the ship sway characteristics under wave loads. The key guide-slider motion of the machine under a 5-DOF load was studied. Then, the guide-slider vibration model with viscous damping and a finite element (FE) structural model of the machine were created. The hammering modal tests and FE modal analysis were used to study its vibration modes. The results show that the guide-slider vibration model and the FE machine model are correct, and there are 6 modal shapes of the machine within 110 Hz.
