【摘要】:半自動雨傘只有一個獨立的狀態(tài)參數(shù);撐開過程中處于壓縮狀態(tài)的彈簧釋放能量,收回時則外力做功轉(zhuǎn)換為彈性勢能,且操作用力遠小于彈簧壓力.分析了雨傘的幾何結(jié)構(gòu)特征和能量變化過程,得到相關(guān)參數(shù)的計算公式,并基于實測數(shù)據(jù)給出具體結(jié)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.

【正文快照】: 文獻[1]基于簡化模型對雨傘自動撐開進行了受力分析;不過,以功-勢能[2]對實際結(jié)構(gòu)進行分析,或許能清楚地說明相關(guān)力學(xué)過程,得到更為具體的結(jié)果. 半自動雨傘結(jié)構(gòu)如圖1所示,幾何參數(shù)滿足 雨傘只有一個獨立的狀態(tài)參數(shù).基于圖1所列雨傘實測數(shù)據(jù),圖2給出相關(guān)參數(shù)的具體變化特征. ,
