利用COMSOL Multiphysics进行船舶轴系回旋振动仿真

Simulation of Whirl Vibration of Ship Shafting With COMSOL Multiphysics

本文利用大型商业有限元软件COMSOL Multiphysics进行船舶轴系回旋振动计算。首先根据轴系布置情况建立仿真模型,确定轴系回旋振动计算的边界条件,以实船轴系为例进行仿真计算并将计算结果与其它软件计算结果比较。通过比较,发现COMSOL Multiphysics有限元仿真方法能较好的解决船舶轴系回旋振动问题。

This paper discusses the calculation of whirl vibration of ship shafting with the software COMSOL Multiphysics, builds the calculation model according to the arrangement of the shafting, defines the constraint conditions for the calculation and compares the result with that from other software, which shows that using COMSOL Multiphysics to calculate is available and reliable.
