摘　　要：相对于传统船型,三体船型具有更优异的流体动力学特性,因此具有更高的航行速度和更小的航行阻力。目前三体船作为一种特种船舶,在军事领域、科研探测和竞技领域有较多的应用。本文介绍计算流体力学和有限元分析技术的基本理论,建立三体船和航行液体环境的有限元模型,分析有限元模型的网格收敛特性,定义三体船型阻力和运动性能分析所需的边界条件,并在STAR-CCM+软件中完成了三体船型的阻力和运动特性分析。Compared with the traditional ship type, trimaran has better hydrodynamic characteristics, so it has higher navigation speed and less navigation resistance. At present, as a special ship, trimaran has more applications in military field,scientific research and exploration and competitive field. This paper introduces the basic theory of computational fluid dynamics and finite element analysis technology, establishes the finite element model of trimaran and navigation liquid environment, analyzes the grid convergence characteristics of the finite element model, establishes the boundary conditions required for the resistance and motion performance analysis of trimaran, and completes the resistance and motion characteristics analysis of trimaran in STAR CCM + software.
