摘  要:通过分析游泳运动员与水的相互作用关系,探索游动过程中阻力与推进力的产生机理,进而提出技术动作的优化方案,实现降低阻力提高推进效率的目的,是当前提升竞技游泳性能最为有效的手段之一。随着计算机科学的快速发展,计算机数值模拟技术在研究游泳阻力与推力的产生机理方面展现出巨大的潜力。然而,由于游泳技术动作及人体结构的复杂性,开展游泳运动的动态仿真研究仍然是计算机数值模拟技术工程应用的一大挑战。研究旨在通过介绍近几十年来基于计算流体力学的游泳动态数值模拟研究进展,指出不同研究方法的特点和局限性,并探讨相关的发展趋势。By analyzing the interaction between swimmers and water,exploring the mechanism of resistance and propulsive force during the swimming process and putting forward the optimized scheme of technical action to achieve the purpose of reducing the resistance and improving the efficiency of propulsion,which is the most effective way to enhance competitive swimming performance.With the rapid development of computer science,computer numerical simulation has shown great potential in the study of the mechanism of swimming resistance and thrust.However,due to the complexity of the swimming technique and the body structure,the dynamic simulation of the swimming exercise is still a challenge in the application of computer numerical simulation.The purpose of this paper is to introduce the progress in numerical simulation of swimming dynamics based on computational fluid dynamics in recent decades,point out the characteristics and limitations of different research methods,and discusses the related development trends.
