摘　　要：利用Rankine源面元法求解潜体兴波问题具有一定的优势,然而随着问题规模的扩大,求解效率将快速下降,使其难以高效运用于大规模以及时域问题研究。结合快速多极子法与传统面元法,可以克服这一局限性,使计算效率和规模大幅度提高。本文将应用多极子面元法求解潜体兴波时域问题,与传统面元法进行比较,证明其高效性;与已有研究结果进行比较,证明其精确性。Using Rankine source panel method for solving wave making problems of submerged body has certain ad-vantages, but with the expansion of the scale of the problem, the solving efficiency will decline rapidly, making it difficult to applied to large-scale problem and time-domain research efficiently. Combining the traditional panel method with the fast multipole method can overcome this limitation, and the computation efficiency and calculation scale will be greatly im-proved. In this paper, the multipole panel method will be used to calculate the wave making problem of submerged body in time domain, and compared with the traditional panel method to prove its efficiency; the results will also be compared with previous studies to prove its accuracy.
