【摘要】:半自动雨伞只有一个独立的状态参数;撑开过程中处于压缩状态的弹簧释放能量,收回时则外力做功转换为弹性势能,且操作用力远小于弹簧压力.分析了雨伞的几何结构特征和能量变化过程,得到相关参数的计算公式,并基于实测数据给出具体结果.
[Abstract]:The semi-automatic umbrella has only one independent state parameter; The spring in the compression state releases the energy in the process of distraction, and when the external force is recovered, the external force is converted into the elastic potential energy, and the operating force is much smaller than the spring pressure. The geometric structure characteristics and the energy change process of the umbrella are analyzed. The calculation formula of the related parameters is obtained, and the concrete results are given based on the measured data.
