为了有效控制充气薄膜结构模拟过程中的展开速度,本文首先从 CV 法(控制体积法)的基本理论入手,通过改变材料和结构的相关参数,对模型的设置进行了改进,以研究影响充气结构展开速度的因素;其次将两种不同充气速率对充气管展开速度影响的模拟结果与实验结果进行了对比,发现数值结果与实验结果趋势基本相同,从而验证了 CV 法的可行性;最后研究了材料参数、充气温度、排气面积等参数对充气管展开速度的影响。研究发现:充气速率越大,充气管的展开速度越大;材料的弹性模量影响较小;质量密度越大、温度越低、排气孔的面积越大,则充气管的展开速度越低。因此,从充气结构的材料本身和结构模型考虑,选用高...

Deployment speed of inflatable structure has long been a parameter which is difficult to control during the inflatable structure simulation process. Firstly, in this paper a modified model by changing the parameters of materials and structures in accordance with the basic theory of CV method (control volume method) is proposed, to study the factors of development speed for inflatable structures. Secondly, comparison of simulation results and experimental results for deployment speed of inflatable tube by two different rates is conducted and numerical results are found having the same trend wit...
