摘要: 中国冰壶在短短几十年中取得了斐然的成绩,但与之相对应的科学研究却相对落后。将计算机仿真技术应用于体育训练中可以有效地帮助运动员了解训练中存在的问题。冰壶在冰面上滑行可以视为刚体的平面运动,可分解为质心的平动和绕过质心的定轴旋转两部分。运用计算机仿真技术模拟冰壶的运动轨迹,通过设置初速度、角速度和刷冰起止时间绘制出冰壶滑行轨迹。通过该系统可以帮助运动员分析投掷冰壶时应施以冰壶水平初速度、旋转角速度,冰壶滑行时刷冰的起止时间对冰壶滑行轨迹的影响。

Abstract: In just a few decades, China’s curling accomplished splendid work. But it’s scientific research falling behind a lot. Applying computer simulation technology in sports training can effectively help the athletes to understand the problems that exist in the training. When curling stone slides on the ice, it can be regarded as two-dimensional motion of rigid body, which can be decomposed into two parts: translation of the center of mass and rotation of a fixed axis around the center of mass. Using computer simulation technology to simulate the curling trajectory, and with the help of this system, the athletes can clearly understand how to throw a certain one, by how much of the beginning of horizontal velocity, angular spin rate and the start and ending time of brush the surface of ice during the slide.

Key words: curling, trajectory, no-collision, simulation
