摘要
对在光滑水平面上可自由移动的球形空腔内作纯滚动的球的运动进行分析,求出球在球形空腔内平衡位置附近做小振动的周期,并和球在可自由移动的球形空腔内做纯滑动的情况作了比较.
In this paper,the author analyses the movement of a ball in a free-moving circular concave on the smooth horizontal surface. The period of micro-amplitude vibration in circular concave near the equibrium position is calculated. Then it is compared with the period of complete gliding in a free-moving circular concave.
