论文摘要

采用有限元和计算流体动力学方法,我们确定了空间体碎片或保持其完整性的条件,当它们渗透到地球大气中时。已经研究了通过行星大气的密集层中太空铁体碎裂的力的起源。结果表明,表面的不规则形状会产生能够导致体内超过铁的拉伸强度阈值的横向空气动力。

Employing the finite element and computational fluid dynamics methods, we have determined the conditions for the fragmentation of space bodies or preservation of their integrity when they penetrate into the Earth's atmosphere. The origin of forces contributing to the fragmentation of space iron bodies during the passage through the dense layers of the planetary atmosphere has been studied. It was shown that the irregular shape of the surface can produce transverse aerodynamic forces capable of causing deformation stress in the body exceeding the tensile strength threshold of iron.
