【摘要】：根據(jù)橡膠氣球的熱力學(xué)性能及門尼模型理論,推導(dǎo)出橡膠氣球膜在充氣與放氣兩個過程中受到的附加壓強與氣球半徑的關(guān)系,并以此推導(dǎo)出不同半徑氣球內(nèi)部的壓強,以及兩個相互連通的氣球體積變化與內(nèi)部壓強的關(guān)系,理論結(jié)果與實驗相吻合.將橡膠氣球模型應(yīng)用于簡易氣墊船研究,建立了氣墊船運動模型,并利用實驗結(jié)果對理論模型進行了修正.
[Abstract]:According to the thermodynamic properties of rubber balloon and the theory of Mooney model, the relationship between the additional pressure and balloon radius in the process of aeration and exhalation of rubber balloon membrane is deduced, and the pressure inside the balloon with different radius is deduced. The relationship between the volume variation of two interconnected balloons and the internal pressure is in good agreement with the experimental results. The rubber balloon model is applied to the study of simple hovercraft, and the motion model of hovercraft is established, and the theoretical model is modified by the experimental results.
