摘要： 在装有100级台阶的斜面上进行单颗粒滚动实验,用统计方法研究小球运动停止位置与小球尺寸、初速度、台阶参数等的关系,给出描述小球在台阶上滚动的运动方程,并讨论了物体在坡面滚动行为与物体尺度、运动初速度、阻力系数、滚动摩擦阻力之间的半定量关系;根据统计方法用计算机模拟实验,给出相应的拟合参数并进行讨论,模拟结果与实验基本吻合。

Abstract: A single particle rolling experiment was carried out on a slope with 100 steps. The relationship between the ball stop position and the size of the ball, the initial velocity and the step parameters were studied by statistical method. The equations of motion were described. And the semi-quantitative relationship between the rolling behavior of the object and the object scale, the initial velocity of the movement, the resistance coefficient and the rolling friction resistance was discussed. According to the statistical method, the corresponding fitting parameters are given and discussed according to the computer simulation experiment. The simulation results are in good agreement with the experiment.

Key words: rolling behavior, sidesteps, granular material
