摘要: 研究对称交错圆盘在水平面上的无滑滚动.给出了交错圆盘的质心坐标和转动矩阵的表达式.讨论了滚动周期长度与圆盘交错的关系.画出了圆盘与地面接触点和交错线段中点的轨迹.

关键词: 圆盘, 轨迹

Abstract: Two symmetric intersected discs roll without slipping on a plane. The coordinates of center of mass and the rotation matrix are given. The relation of space period and intersected angle is discussed. The trajectories of contact point and midpoint of intersected segment are plotted.

Key words: discs, trajectory
