为了提高救生舱舱体的抗冲击能力,针对现有的正置式肋板布置形式,笔者提出一种斜置式肋板布置形式。首先通过三维软件对两种布置形式的救生舱侧壁进行三维建模,并采用LS-DYNA进行显示动力学分析,得到不同布置形式下侧壁受爆炸冲击的应力分布情况以及危险节点、单元的位移和等效应力的时间历程曲线。研究结果表明,与正置式肋板的布置形式相比,斜置式肋板具有明显的抗冲击优势。 In order to improve the impact resistance of the cabin of the life-saving module, aiming at the existing layout of the right-side rib, the author proposes a layout of the inclined rib. Firstly, the three-dimensional modeling of the sidewalls of the two types of rescue shelter is carried out by using the three-dimensional software and the dynamic analysis of the display is carried out by LS-DYNA. The stress distribution of the sidewall under different layouts and the impact of dangerous nodes and elements Displacement and equivalent stress time history curve. The results show that the inclined rib has obvious impact resistance compared with the layout of the positive rib.
