| 摘 要： | 水下滑翔机的附加质量对其运动状态影响较大，本文采用了Hess-Smith（面元法）方法编制了计算任意三维物体附加质量的程序，利用Gambit软件对水下滑翔机进行网格划分，计算出实验室所研制的水下滑翔机附加质量，同时利用CFD（Computational Fluid Dynamics）技术，结合动网格技术和UDF（User-Defined Function），对水下滑翔机进行了PMM（Planar Motion Mechanism）试验模拟，并与Hess-Smith方法得到的结果进行对比，分析两者之间的特点和各自优势。

Numerical method for added mass of an underwater glider |

| Abstract: | Added mass of an underwater glider is quite important for the motions of glider. In this paper, the added mass of an arbitrary three-dimensional body is obtained through Hess-Smith method. Then an underwater glider which was designed by our laboratory is meshed by Gambit software in order to obtain its added mass. Besides, the Planar Motion Mechanism (PMM) tests of the glider are simulated by using CFD software, dynamic mesh technique and UDF. By compar-ing with the Hess-Smith results, the characters and advantages of Hess-Smith method and PMM are analyzed. |
