摘　　要：分析了麦克斯韦滚摆在下降过程中的势能、平动动能与转动动能的相互转化,总机械能保持守恒;进一步分析了麦克斯韦滚摆运动到最低点的力学过程,麦克斯韦滚摆质心速度反向的原因,并给出了悬线最大张力的近似公式.The mutually transfer among the potential energy,translational kinetic energy and rotational kinetic energy in the falling movement process of Maxwell roll pendulum was analyzed,while the total mechanical energy was conserved.The mechanical process of Maxwell rolling pendulum moving to its lowest point was analyzed,the reason for the reverse of the mass center velocity of the Maxwell rolling pendulum was explained.And the approximate formula for the maximum tension of the suspension line was provided.

关 键 词：麦克斯韦滚摆 机械能守恒 动能 势能
