摘要
分析了锥体上滚运动的动力学方程,并通过受力分析方法求解出锥体上滚的条件,结果与通过能量最低原理得出的结论一致.
The dynamic equation of the roll-up motion of cone was analyzed,and the condition of the roll-up motion of cone was obtained by using force analysis method.The results were consistent with those obtained by using the minimum energy principle.
