摘要
为实现船舶振动噪声的快速预报,利用有限元软件MSC.PATRAN的命令语言PCL,借助开发工具MATLAB的GUI,开发程序实现船舶结构的参数化建模以及振动噪声的自动计算.利用所开发的程序,对某船舶的机舱与基座结构参数进行修改,得到修改前后的船体振动分布与水下噪声谱,从而实现了船舶设计阶段的振动噪声快速评估.参数化建模是一种实现船舶振动噪声评估快速有效的手段.
Aiming at the quick prediction of ship vibration and noise,we compile a program for the parametric modeling of the ship structure and the automatic calculating of vibration and noise by using the command language PCL of FEA software MSC.PATRAN and the GUI of MATLAB.By means of the program developed,the structure parameters of the cabin and the equipment base are modified and the vibration distribution of hull and underwater noise spectra are obtained.The rapid assessment of vibration and noise of the ship is carried out by means of parametric modeling.
