摘要
利用涡卷弹簧受载、卸载时能量转化的特点,将其与发电机结合可以取代电动自行车上的蓄电池。设计了一种涡卷弹簧储能式发电系统,对涡卷弹簧进行了参数设计与三维建模,并对涡卷弹簧的收紧过程进行了有限元分析,得到其在收紧过程中的簧片位移与应力分布规律以及在完全收紧时应力集中区域处各层弹簧上的最大应力呈现出沿径向先增大后减小的变化规律,确定了涡卷弹簧储能时的危险截面,对提高涡卷弹簧储能式发电系统的可靠性具有重要的理论与实际意义。
By using the characteristics of the energy conversion of the scroll spring during loading and unloading,it can be combined with the generator to replace the battery on the electric bicycle.A scroll spring energy storage power generation system is designed.The parametric design and 3 D modeling of the scroll spring are carried out.The finite element analysis of the tightening process of the scroll spring is carried out.It is obtained that the reed displacement and stress distribution law in the process of tightening of the scroll spring as well as the maximum stress on each layer of spring at the stress concentration region when fully tightened show a change law that increases first and then decreases in the radial direction.The dangerous section of the scroll spring is determined.It has important theoretical and practical significance for improving the reliability of the scroll spring energy storage power generation system.
