| 1. | Firstly , the process of fold and deployment was divided into several steps . secondly , the relative geometry results of the last simulation step was picked up as the initial geometry configuration of current step , using the restarting technology provided by fem programs , then the models of a inflatable structure with an paraboloid shape were established
然后,基于ls - dyna970中的airbag模型,建立了卷曲折叠空间充气展开管的有限元模型,运用控制体积法将充气管离散为若干连续的腔,成功模拟了其充气展开过程,并研究了不同充气速率对充气管展开过程的影响规律。 |
