按照飞轮的简易设计方法，忽略等效转动惯量中的变化部分，对于机构来说，最大的盈亏共出现在动能变化最大两个位置，为此再作出机构的总能量变化。-According to the simple design method of the flywheel, ignoring the change in the equivalent moment of inertia, the maximum profit and loss appear in the maximum two positions of the kinetic energy change for the organization, and then make the total energy change of the mechanism.
