摘要
针对纤维预浸织物管在充气展开过程中的力学特性,本文提出了一种各向同性剪切模型,用于描述在充气压力作用下预浸织物的剪切行为变化,并利用该模型结合有限元法模拟了折叠管的充气展开过程,结果表明,剪切特性对纤维预浸织物管的充气展开过程有明显的影响.
In view of dynamical characteristics of the fabric prepreg material in the deployment process, a shear model with isotropy is proposed to describe the shear properties with the effect of inflation pressure, through finite element analysis, the inflation and deployment process was simulated. The results show that shear properies have a distinct effect on deployment process of the fabric prepreg tube.
