【摘要】 利用微分定义法导出了阿基米德螺线上一点的切线和径线垂直线的夹角公式,并且得到了夹角变化规律。选用合适的螺线槽段,使得变惯量飞轮的操纵力远小于可移动质量块的离心力。由于飞轮自身的转动惯量能连续变化使得传动机构也能简化。在这基础上研究了滑块沿径向做等速运动时飞轮动能变化规律,得到输入输出扭矩的变化规律。结果显示输入较小的控制扭矩能得到飞轮较大的输出扭矩,应用于储能能提高传动效率,在实现短时间输入输出大扭矩场合能减小驱动装置的功率。更多还原

【Abstract】 A formula for the angle between the tangent line and the radial line about the same point on Archimedes spirals is derived by the differential definition method,and the pattern of the change of angle is also found. When appropriate spiral slot sections are selected,the force required to manipulate the variable inertial flywheel is far less than the centrifugal force caused by the movement of the movable masses. The transmission mechanism is simplified because the inertia moment of the flywheel can continuously change. Then the kinetic energy change pattern of the flywheel when its masses are moving in radical direction with a uniform velocity is gained to acquire the change pattern of the input-output torque. The result shows that it is possible to acquire a considerable output torque when a relatively small manipulation torque is inputted,and that the above device can be used to improve the transmission efficiency when used in the field of energy storage. The reduction of power of equipments which input or output big torque in a short time is realized hence.更多还原
